Semi-dynamic flip-flop
Abstract:
A semi-dynamic flip-flop is provided. A selecting circuit selects an input signal from a data signal and a test signal. A charging/discharging circuit charges/discharges an intermediate node according to the input signal, a clock signal and a modulation signal. A first storage circuit stores electric potential of the intermediate node. An adjusting circuit generates an adjustment signal according to the clock signal and the potential of the intermediate node. An output signal adjusts electric potential of an output node according to the clock signal and the potential of the intermediate node. A second storage circuit stores the potential of the output node. A reset circuit sets or resets the potential of the output node. A switch, connected between the adjusting circuit and the charging/discharging circuit, is turned on when the semi-dynamic flip-flop is in a normal operation mode.
