ELECTRONIC CIRCUIT WITH A CLOCK SWITCH

摘要

An electronic circuit comprises clocked functional circuits which receive a clock signal via a clock switch. The clock switch contains an enabled non-inverting driver which switches a connection between a power supply input and a clock output on and off under control of a clock signal only when the clock switch is enabled by an enable signal. The clock switch also contains a transmission switch coupled between a clock input and the clock output. The transmission switch is controlled from the enable input and makes a conductive connection between the clock input and the clock output only when the clock switch is enabled by the enable signal. As a result, transitions in the clock signal reach the functional circuits with less delay and power take-up needed to drive the clock signal is distributed so that there is less supply bounce.
