Abstract

See full text

A technique implements differential digital logic circuits with a differential clock distribution network using standard cell differential clock gater circuits to reduce area, delay, power consumption in integrated circuits. An apparatus includes a first terminal configured to receive a clock signal, a second terminal configured to receive a complementary clock signal, and a third terminal configured to receive a clock control signal. The apparatus includes a latch circuit configured to generate a latched version of the clock control signal based on a version of the clock control signal, a version of the clock signal, and a version of the complementary clock signal. The apparatus includes a combinatorial circuit configured to generate a gated clock signal and a gated complementary clock signal based on the version of the clock control signal, the version of the clock signal, and the version of the complementary clock signal.
