SEQUENCED PULSE-WIDTH ADJUSTMENT IN A RESONANT CLOCKING CIRCUIT

摘要

A clock driver control scheme for a resonant clock distribution network provides robust operation by controlling a pulse width of the output of clock driver circuits that drive the resonant clock distribution network so that changes are sequenced. The clock driver control circuit controls the clock driver circuits in the corresponding sector according to a selected operating mode via a plurality of control signals provided to corresponding clock driver circuits. The pulse widths differ for at least some of the sectors during operation of digital circuits within the integrated circuit having clock inputs coupled to the resonant clock distribution network. The different pulse widths may be a transient difference that is imposed in response to a mode or frequency change of the global clock that provides an input to the clock driver circuits.
