Abstract:
A hazard-free minimal-latency flip-flop (HFML-FF) is provided. A master latch includes an input to accept a D1 signal, an input to accept a clock signal, an input to accept an inverted shadow-D2 signal, and an output to supply a D2 signal. The master latch has an input to accept a shadow-D1 signal, an input to accept the clock signal, and an output to supply a shadow-D2 signal and the inverted shadow-D2 signal. The slave latch has an input to accept the D2 signal, an input to accept the clock signal, an input to accept an inverted shadow-Q signal, and an output to supply a Q signal. The slave latch has an input to accept either the D2 signal or the shadow-D2 signal, an input to accept the clock signal, and an output to supply a shadow-Q signal and the inverted shadow-Q signal. The design may use clocked inverters or pass gates.
