Differential Amplifier Square wave can be defined as a non sinusoidal periodic waveform that can be represented as an infinite summation of sinusoidal waves. It has an amplitude alternate at a regular frequency between fixed minimum and maximum value with the same duration.
Square wave generator are generally used in electronics and in signal processing. The square wave is the special case of rectangular wave. The square wave generator is just like a Schmit trigger circuit in which the reference voltage for the comparator depends on the output voltage. It is also said to be astable multivibrator. Square wave generator can be constructed using Schmitt trigger inverters like TTL. It is the easy way to make a basic astable waveform generator.
Non-Inverting Comparator In this circuit input is applied to the non-inverting terminal of op-amp. Inverting terminal is kept at reference potential. In this case the reference voltage is zero. Figure below shows the Non-Inverting Comparator. The op-amp is in open loop configuration and hence its output is in saturation. Dt Sheet. This DC output voltage is called output offset voltage.
The offset voltage can be expressed as below. In the inverting amplifier of fig. Here, non-inverting input of OP-Amp is earthed, so the voltage is expressed as DC input voltage at both ends of this resistance, and this is amplified by OP-Amp.

The present invention relates to emergency power supplies. In particular, the present invention relates to an emergency power supply coupled directly to the external and internal lines.
In case of a sudden power outage, it is common for homeowners and businesses alike to rely on emergency power supplies to meet at least part of their power consumption needs. A simple emergency power supply commonly may comprise nothing more than one or more DC batteries coupled to a discharge unit, or inverter, which converts the DC battery voltage to an AC signal, useful in a VAC, 60 Hz circuit. The non-inverting input of linear amplifier is coupled to ground.
Another input of NAND gate is coupled to an output of an overcurrent. USA - Emergency power supply - Google Patents In this amplifier the input signal and output signal are in phase i. The following circuit diagram shows the non-inverting amplifier using op-amp.
The input signal is applied at the non-inverting terminal of op-amp. Due to the virtual ground concept, the inverting terminal of op-amp is also appears to be at the same potential Vin. Power Supply 2. CRO 3. Function Generator THEORY: Cathode ray oscilloscope is one of the most useful electronic equipment, which gives a visual representation of electrical quantities, such as voltage and current waveforms in an electrical circuit.
It utilizes the properties of cathode rays of being deflected by an electric and magnetic fields and of producing scintillations on a fluorescent screen. Since the inertia of cathode rays is very small, they are able to follow the alterations of very high frequency fields and thus electron beam serves as a practically inertia less pointer. When a varying potential difference is established across two plates between which the beam is passing, it is deflected and moves in accordance with the variation of potential difference.
When this electron beam impinges upon a fluorescent screen, a bright luminous spot is produced there which shows and follows faithfully the variation of potential difference. From the trace of the signal several measurements can be made. Measurement of D. Voltage: Deflection on a CRO screen is directly proportional to the voltage applied to the deflecting plates.
Therefore, if the screen is first calibrated in terms of known voltage. The amount of deflection so produced multiplied by the deflection sensitivity, gives the value of direct voltage. C voltage: To measure the alternating voltage of sinusoidal waveform, The A.
The voltage deflection sensitivity band switch Y-Plates and time base band switch X-Plates are adjusted such that a steady picture of the waveform is obtained on the screen. The vertical height l i. When this peak-to-peak height l is multiplied by the voltage deflection sensitivity n i. From this we get the peak voltage Vp. This rms voltage Vrms is verified with rms voltage value, measured by the multimeter. Measurement of Frequency: An unknown frequency source signal generator is connected to yplates of C.
Time base signal is connected to x — plates internally connected. We get a sinusoidal wave on the screen, after the adjustment of voltage sensitivity band switch Y-plates and time base band switch X-plates. To calculate the frequency of the observed signal, one has to measure the period, i.
Connect the CRO probes to the output of function generator. Keep frequency of the function generator at zero and amplitude to any value. Observe the peak values Vp of the wave currently selected. Observe the Time-Period T of the wave selected. Change the both voltage and time period scale and repeat the step 2 to step 5 for three different readings. From Function generator: Input voltage: …. Make the connections as shown in the circuit diagram.
Connect Function Generator and Oscilloscope in correct polarities. Take the readings carefully. Lissajous pattern may be a straight line, an ellipse or a circle depending on the frequency, phase and amplitude of the two signals. Hence fy can be found if fx is known. An oscillator of unknown frequency is connected to the vertical plate of the CRO and standard oscillator of known frequency is connected to horizontal plate. Adjust the voltage of the two oscillators to give a pattern of a suitable size.
Vary slightly the frequency of the test oscillator until a simple Lissajous pattern is obtained. Read known frequency fx. Calculate fy by the given formula. Repeat the step 3 and 4 and take five different readings. Experiment-2b phase angle between two signals of the same frequency using CRO. Observe and trace the Ellipse on tracing paper and Measure Y intercept and Y peak.
Note down the frequency of wave applied from Function Generator. Millimeter 3. Micro Ammeter 4. Diodes 1N 2. The plane dividing the two halves or zones is called PN junction. The N-type material has high concentration of free electrons, while P-type material has high concentration of holes.
Therefore, at the junction there is a tendency for the free electrons to diffuse over the P-side and holes the N-side. This process is called diffusion. As the free electron moves across the junction from N- type to P-type, the donor irons become positively charged. Hence a positive charge is built on the N-side of the junction.
The free electrons that cross the junction uncover the negative acceptor ions by filling in the holes. Therefore, a net negative charge is established on the P-side of the junction. This net negative charge on the P-side prevents further diffusion of electron in to the P-side.
Similarly, the net positive charge on the N-side repels the holes crossing from P-side to N-side. Thus a barrier is set-up near the junction which prevents further movement of charge carriers. As the consequence of the induced electric field across the depletion layer, an electrostatic potential difference is established between P and N region, which is called the potential barrier, junction barrier, diffusion potential, or contact potential, VO.
The magnitude of the contact potential VO varies with doping levels and temperature. VO is 0.

If the input is negative, then the output will be positive. Op amps generally come in the form of an integrated circuit , or chip. What differentiates the inverting op amp from other op amp circuits is the configuration of the inputs and negative feedback loop. It strongly resembles the non-inverting op amp with the input and ground configurations exchanged.
As with other op amp circuits, the functionality of the inverting op amp is determined by how the op amp is used in the circuit. This includes the input configuration, feedback loop, and resistor values. In this article we will cover the essentials of the inverting op amp. We will analyze the inverting op amp circuit and derive the formulas for gain and output. What is An Inverting Op Amp? An inverting op amp is a type of amplifier that uses an op amp to invert the input the signal.
This means that the polarity of the output will always be opposite that of the input. This is represented by the negative sign in the gain formula, which we will derive below. The inverting op amp is a quintessential example of an op amp circuit. Op amps can be used in many configurations in order to create circuits with different functionalities. Like most op amp circuits, the inverting op amp uses a negative feedback loop that connects the output to the inverting input.
In contrast, a positive feedback loop would have the output connected to the non-inverting input. The inverting op amp circuit is almost identical to the non-inverting op amp in terms of circuit construction. The primary difference is the reversal of the inputs to the circuit. An inverting amplifier using opamp is a type of amplifier using opamp where the output waveform will be phase opposite to the input waveform.
The input waveform will be amplifier by the factor Av voltage gain of the amplifier in magnitude and its phase will be inverted. In the inverting amplifier circuit the signal to be amplified is applied to the inverting input of the opamp through the input resistance R1.
Rf is the feedback resistor. Rf and Rin together determines the gain of the amplifier. Negative sign implies that the output signal is negated. The circuit diagram of a basic inverting amplifier using opamp is shown below. Inverting amplifier using opamp The input and output waveforms of an inverting amplifier using opamp is shown below. The graph is drawn assuming that the gain Av of the amplifier is 2 and the input signal is a sine wave.

Simulation result is as shown in figure A power supply is an essential part of each electronic system from the simplest to the most complex. It is thus pertinent at this point to review some basic facts and terms concerning digital waveforms. This rms voltage Vrms is verified with rms voltage value, measured by the multimeter. Note that the output can source drive fairly high currents into an external load via Q1 under this condition, but that the actual inverter stage consumes near-zero current, since Q2 is cut off. Thus, the basic CMOS inverter can be used with any supply in the V range, has a very high input impedance, consumes near-zero quiescent current, has an output that switches almost fully between the two supply rails, and can source or sink fairly high output load currents. |
