Such a comparator is also called a limit detector as it detects the particular positive level of the input beyond which input goes high. The resistance R1 and R2 can be used to set the trip point ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input res… ...

Figure 2 shows the circuit's output-voltage variation for 10 cycles of a sinusoidal input signal with an amplitude of 10 mV and a frequency of 100 kHz. The measured output variation is 200 mV ...

On the other hand, precise detectors based on op amps are rather slow. They are therefore not well-suited for measuring pulses of a few nanoseconds’ duration. The circuit in Figure 1 offers both good ...

It is by no means a good op-amp by the standards on any era but 1964, as does not have a very high gain, has no short-circuit protection, and requires an external capacitor for frequency ...

FIGURE 1 DEMONSTRATES A one-way switchedcapacitor gain stage circuit, performing a voltage gain of AO = C1/C2 only during the decreasing trail of the input signal VI (with VJ ...
