RESONANT CLOCK DISTRIBUTION NETWORK ARCHITECTURE FOR TRACKING PARAMETER VARIATIONS IN CONVENTIONAL CLOCK DISTRIBUTION NETWORKS

摘要

A resonant clock distribution network architecture is proposed that enables a resonant clock network to track the impact of parameter variations on the insertion delay of a conventional clock distribution network, thus limiting clock skew between the two networks and yielding increased performance. Such a network is generally applicable to semiconductor devices with various clock frequencies, and high-performance and low-power clocking requirements such as microprocessors, ASICs, and SOCs.
