Abstract
A differential comparator, working with microwaves and using only one clock, is disclosed. This comparator has a differential amplifier and a divergence circuit in which are included two voltage level translators. The coupling between the amplifier and the divergence circuit is made at the gates of the load transistors of the divergence circuit. Two insulation transistors, working in either saturated mode or resistive mode, are used to provide the amplifier with an automatic control loop which stabilizes all the rest voltages. The clock signal, applied to two transistors which short circuit the two feedback transistors of the divergence circuit, controls the passage from the measuring phase to the divergence phase.
