ABSTRACT:
The comparison circuitry of a comparator is isolated from noise on the power supply and ground by utilizing transistors operating in the forward-active region to isolate the comparison circuitry. The comparison circuitry is further isolated from random noise spikes by utilizing delay and switching circuitry to control the duration of the comparison.
