When a signal glitches, the logic receiving the signal can change response, charging and / or discharging nodes within the logic and dissipating power. Providing glitch-free signals can reduce the number of times nodes are charged and / or discharged, reducing power consumption. A technique for removing glitches is to insert a storage element that samples the signal after the signal change is complete to produce a glitch-free output signal. The storage element is enabled by a "ready" signal that has a delay that matches the delay of the circuit generating the signal. This technique can prevent the output signal from changing until the final value of the signal is reached. The output signal only changes once, typically reducing the number of times nodes in the logic receiving the signal are charged and / or discharged, also reducing power consumption.
