SETTING SWITCH SIZE AND TRANSITION PATTERN IN A RESONANT CLOCK DISTRIBUTION SYSTEM

摘要

Recycling energy in a clock distribution network is provided. A method includes creating a resonant clocking circuit including a clock grid. The method further includes providing resonant structures distributed in the clock grid. The method further includes providing switches that control the resonant structures to switch between a non-resonant mode and a resonant mode. The method further includes determining a switch size that minimizes power consumption of the resonant clocking circuit by iteratively increasing sizes of the switches and, for each iterative increase in size, determining power consumed by the resonant clocking circuit.

1. A method for providing a resonant clocking circuit comprising:
creating a clock grid including a plurality of resonant structures distributed in the clock grid; providing a plurality of programmable switches that switch a respective one of the plurality of resonant structures between a non-resonant mode and a resonant mode, each of the plurality of programmable switches being controllable to progressively energize the respective one of the plurality of resonant structures; and determining a transition pattern for controlling the plurality of programmable switches to progressively energize the plurality of resonant structures.
