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 ...

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 ...

Digital comparison is considered an important method used in digital systems while executing arithmetic or logical operations. It’s designed to compare the relative magnitudes of binary numbers.

The ATtiny85’s Analog Comparator function is perfectly suited for such a tester. One input of the comparator is biased such that there is a 51 ohm resistor between the input and ground.
