CMOS d-type flip-flop circuits.

摘要

A CMOS D-type flip-flop circuit stage for avoiding the possibility of feedthrough includes a non-overlapping clock generator section having a true clock output and a complement clock output. The flip-flop circuit includes a master section formed of a first transfer gate, a first regenerative transistor and a first inverter gate. The flip-flop circuit further includes a slave section formed of a second transfer gate, a second regenerative transistor and a second inverter gate. The clock generator provides a two-phase non-overlapping clock for clocking both the master and slave sections so as to prevent inadvertent racethrough of data input to successive stages.
