Abstract
An MOS comparator circuit for sensing small voltage differences between two inputs is disclosed. The response time of the comparator circuit is improved by providing both a differential amplifier circuit and an output circuit with faster response times. The response time of the differential comparator circuit is improved by preventing the current-mirror from turning off. The response time of the output circuit is improved by limiting the input voltage to the inverter of the output circuit to a range of slightly greater than the balance-point voltage and slightly less than the balance-point voltage of the inverter. The difference between the response of the comparator circuit to large amplitude input voltages and small amplitude input voltages is also improved.
