C-mos differential sense amplifier

Abstract From the Canadian patent

A C-MOS sense amplifier detects voltage differences between the signals applied to its inputs in correspondence with transitions of a clock signal. It comprises a level converter, a sense circuit and a feedback circuit which, are inactive in a first inactive phase of the clock signal while in a second active phase, immediately following a clock signal transition, the sense amplifier reaches an operating point necessary to activate the level converter and the sense circuit, and hence a high positive feedback is set up which switches the sense circuit. Finally following the corresponding level transition of a delayed clock signal, the feedback signal generated by the feedback block reduces …
