Abstract:
1. A wide bandwidth resonant clock distribution comprising: a clock grid configured to distribute a clock signal to a plurality of components of an integrated circuit; a tunable sector buffer configured to receive the clock signal and provide an output to the clock grid, wherein the tunable sector buffer is programmable to set latency and slew rate of the clock signal; at least one inductor; at least one tunable resistance switch; and a capacitor network, wherein the inductor, tunable resistance switch, and capacitor network are connected between the clock grid and a reference voltage; and wherein the at least one tunable resistance switch comprises at least one switch and at least one variable resistor and wherein the at least one tunable resistance switch is programmable to dynamically switch the at least one inductor in or out of the clock distribution to effect at least one resonant mode of operation or a non-resonant mode of operation identified based on a frequency of the clock signal.
