摘要： A wide bandwidth resonant clock distribution comprises 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, at least one inductor, at least one tunable resistance switch, and a capacitor network. The tunable sector buffer is programmable to set latency and slew rate of the clock signal. The inductor, tunable resistance switch, and capacitor network are connected between the clock grid and a reference voltage. 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 based on a frequency of the clock signal.
