Title: Amplifier circuit

Abstract: A current mirror amplifier (CMA) with controlled current gain, the current gain being changed, for example, responsive to the output condition of a comparator in which the CMA is used in a differential signal combining circuit. In such a comparator application the switched gain of the CMA imparts hysteresis to the comparator characteristics.
