ABSTRACT:
A differential flip-flop (400) has an output stage (402) with first and second input terminals (X1, X2), first and second output terminals (Q, Qb), a first voltage supply terminal (Vss), a first transistor (435) having a first current-handling terminal connected to the first output terminal (Q), a second current-handling terminal connected to the second output terminal (Qb), and a first control terminal connected to a clock signal (C). A second transistor has a third current-handling terminal connected to the first output terminal (Q), a fourth current-handling terminal connected to the voltage supply terminal (Vss), and a second control terminal connected to a first input terminal (X1) of the output stage. A third transistor (440) has a fifth current-handling terminal connected to the first output terminal (Q), a sixth current-handling terminal connected to the voltage supply terminal (Vss), and a third control terminal connected to the second output terminal (Qb).
