Abstract:
A flip-flop comprising:a. a differential output stage having differential first and second input terminals and complementary first and second output terminals; b. a transistor having a first current-handling terminal connected to the first output terminal, a second current-handling terminal connected to the second output terminal, and a control terminal; c. wherein the differential output stage includes a cross coupled circuit having a cross coupled transistor configured to continuously receive power from a positive power supply voltage, wherein a gate of the cross coupled transistor is connected to the second output terminal; d. a differential input stage having differential third and fourth input terminals and complementary third and fourth output terminals connected to the first and second input terminals, respectively; and â€ƒwherein the differential input stage includes another transistor having a current-handling terminal continuously connected to VSS and a gate connected to the third input terminal, and another cross coupled circuit including another cross coupled transistor having a gate connected to the fourth output terminal.
