Abstract
Noise may be reduced by delaying signal propagation outside of a time window when a change in another signal is expected. A time window may be defined between the change of the first clock signal and the change of the second clock signal during which a third signal, such as a data signal, does not propagate through the circuit. When a change occurs in a third signal after the first clock signal change while the first clock signal is at a different level than a second clock signal, propagation of the third signal change may be delayed until a change in the second clock signal is received. Delayed propagation may be achieved through a latch and hold circuit with no metastability.
