Abstract
A master-slave flip-flop circuit with a master latch and slave latch has clock generating circuitry which generates a gated clock signal based on the clock signal and a gating control signal. When the gating control signal has a first value, then the gated clock signal has a value dependent on the clock signal, while when the gating control signal has a second value then the gated clock signal has a fixed value independent of the clock signal. At least one component of the master-slave flip-flop circuit is controlled by the gated clock signal so that dynamic switching power can be reduced. The gating control signal is dependent on the input signal or a signal within the master latch and is independent of a slave signal in the slave latch and the output signal of the flip-flop.
