Figure 1 Basic improved comparator equivalent schemes. Circuit 1: Comparator Realized using BJTs The comparator shown in Figure 2 is formed by bipolar transistors VT1, VT2, and the three status ...

Designing a circuit to switch on a light at dusk and off at dawn is straightforward, and many such designs have been featured ...

These circuits used negative feedback, which normally keeps the op amp operating in the linear region. However, op amps can also be used as comparators, which causes them to operate non-linearly. The ...

Comparator Classification Over-zero voltage comparator: a typical amplitude comparison circuit with the circuit diagram and transmission characteristic curve shown in the figure. Voltage ...
