A differential amplifier is provided to amplify a small differential signal between input signal Vin and reference signal Vref and produce a pair of complementary high level output signals with a wide range of Vref values. The Wide Range Dynamic Differential Amplifier (WRDDA) shown in the figure consists of three parts: the steering circuit 1, the master flip-flop 3, and the slave flip-flop 5. The operation sequence is as follows: at quiescence, the reset clock øR is on, holding the output pair VO and VO at ground potential. Nodes 7 and 9 are precharged to an equal potential. The input node 11 and the reference node 13 are continually connected to the input terminal Vin and the reference terminal Vref, respectively.
