ABSTRACT:
A comparator circuit of one type, prior to this invention, had a reliability problem due to an undesirable conductive path, and had limited speed due to stray capacitances. Reliability is achieved through separate triodes for coupling an inverted storage pulse to a primary electrode of each of two triodes of a differential amplifier. Speed is achieved through coupling a transistor across the other primary electrodes of the differential amplifier, the transistor's gate electrode receiving a narrow pulse upon termination of the storage pulse.
