The response to a fast pulse will rise sharply for the first 50% of the output swing, then taper off during the remaining portion of the edge. Calculations show that the 10 to 90% waveform risetime is 30 times greater than the 0 to 50% risetime when the cable is skin effect limited...
Figure 1. Op amp output saturation produces a clipped signal. Image used courtesy of Robert Keim Saturation leads to a complete loss of correspondence between the input waveform and the output waveform. However, output swing performance can degrade even before the saturation point is reached. Applic...
Figure 1: One approach to producing higher voltage op-amp outputs is to add complementary booster transistors to a basic device such as the Analog Devices LT1055to take advantage of the input characteristics of the op-amp; this design takes the output to ±120 V. (Image source: Analog Devic...
The input & output waveforms of non-inverting op-amp waveforms are shown below. The signal which needs to change is given to the +ve terminal of the op-amp whereas the –ve terminal is connected to GND with the help of an R1 resistor. The input (Vin) & output (Vout) voltages are w...

If a sinusoidal wave input is applied at a non-inverting terminal of the op-amp comparator while the inverting input is grounded through a voltage divider as shown in the figure, draw the output waveform of the comparator. As the input is applied at a non-inverting terminal, we are therefo...
Low Noise, Low Input Offset Voltage CMOS Operational Amplifiers (Op Amps)Low-Side Current Sensing Circuit –Transient Response simulation This circuit simulates the transient response at the low-side current sensing with Op Amps. You can observe the fluctuation of the output voltage when the source...
Investigate the effect of LM358’s slew rate on the output waveform by revisiting the setup from Exercise 2 (Figure 3). Maintain the same connections and gain setting resistors. Set the signal generator to output a 1Vp-p, Bipolar, Square wave. ...
Although the simple voltage comparator circuit using either an ordinary operational amplifier or a special comparator is often adequate, the input waveform may be slow or have noise superimposed on it. This can result in the possibility that the output will switch back and forth several times as ...
The output waveform may be offset with respect to ground if the inverting input of the threshold detector, A1, is offset with respect to ground. The generator may be made independent of temperature and supply voltage if the detector is clamped with matched zener diodes as shown in Figure 28....
