Design and Analysis of Actively-Deskewed Resonant Clock Networks

Abstract

Active deskewing is an important technique for man- aging variability in clock distributions but introduces latency and power-supply-noise sensitivity into the resulting networks. In this paper, an adaptively deskewed resonant clock network, based on an injection-locked distributed differential oscillator , is described, in which the delay lines required for deskewing are incorporated into the injection-lock source, dramatically improving jitter immu- nity. A power management system based on aut
