ABSTRACT:
A compound logic flip-flop. The flip-flop includes a plurality of input stages, wherein each of the input stages is coupled to receive at least one input signal and a clock signal. Each of the plurality of input (i.e. ‘master’) stages is configured to perform a corresponding input logic function during a first phase of a clock cycle and to store a result of the corresponding input logic function. The flip-flop further includes an output (i.e. ‘slave’) stage coupled to receive the clock signal and the results of the input logic functions from each of the plurality of input stages. The output stage is configured, during a second phase of the clock cycle, to logically combine the results of the input logic functions by performing an output logic function and provide an output signal based on a result of the output logic function.
