A comparator circuit is an electronic circuit that compares the magnitudes of two input voltages and produces an output based on the comparison result. The output of a comparator is typically a binary signal, indicating whether one input is greater than the other. It's a fundamental building block in electronics and finds various applications in digital systems, control systems, instrumentation, and more.
The basic operation of a comparator involves comparing the voltage levels of its two inputs, often referred to as the inverting (-) input and the non-inverting (+) input. The comparator's output state is determined by the relationship between these inputs:
If the voltage at the non-inverting input is higher than the voltage at the inverting input, the comparator
