ABSTRACT:
A fully differential phase and frequency detector utilizes a multi-function differential logic gate to implement a differential AND gate operation and provides a fully differential D-flip-flop. The multi-function differential logic gate has four inputs, which can be grouped into two pairs of true and complement signals. By selectively re-assigning the inputs to different signal pairs, the differential logic gate can be made to provide one of either simultaneous AND/NAND logic operations or simultaneous OR/NOR logic operations. The differential D-flip-flop is implemented following a master/slave configuration and is response to the true and complement forms of an input clock signal, an input reset input, and input data signal, and also provides true and complement forms of an output signal. All components within the phase and frequency detector are exemplified in CML circuit configuration.
