CLOCK GATED CIRCUIT AND DIGITAL SYSTEM HAVING THE SAME

摘要

PURPOSE: A clock gated circuit and a digital system including the same are provided to maintain the performance of a flip-flop and to reduce power consumption. CONSTITUTION: A pulse generator(120) receives a clock and generates a pulse and an inverse pulse. A pulse level converter(140) receives the pulse and the inverse pulse and converts a level of the pulse in response to an active signal. The pulse generator includes inverters which generates a delay clock, a logical circuit which outputs the inverse pulse, and an inverter which outputs the pulse.
