Comparator

In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals V + {\displaystyle V_{+}} and V − {\displaystyle V_{-}} and one binary digital output V o {\displaystyle V_{\text{o}}} . The output is ideally
