Voltage comparators are high gain differential input-logic output devices. They are specifically designed for open-loop operation with a minimum of delay time. Although variations of the comparator are used in a host of applications, all uses depend upon the basic transfer function. Device operation is simply a change of output voltage dependent upon whether the signal input is above or below the threshold input.
