Abstract
A high speed differential to single ended comparator manufactured with a CMOS process utilizes parasitic bipolar transistors for providing a high transconductance, a low offset voltage, a low input to output response time, small physical area, improved matching characteristics, and reduced complexity and number of process steps involved in manufacturing the device. A feedback circuit maintains the output current constant when the input signals are in a steady state.
