Comparators

A Comparator is a circuit that accepts two voltages or currents and then switches the output showing which of the two is bigger. Comparators are found in components such as analogue to digital converters (ADCs). Comparators are like operational amplifiers except a comparator is designed specifically to operate with positive feedback and output saturated at one power rail or the other.
