Low latency analog adaptive clocking

Abstract:

An apparatus is provided for low latency adaptive clocking, the apparatus comprises: a first power supply rail to provide a first power; a second power supply rail to provide a second power; a third power supply rail to provide a third power; a voltage divider coupled to the first, second, and third power supply rails; a bias generator coupled to voltage divider and the third power supply rail; an oscillator coupled to the bias generator and the first supply rail; and a clock distribution network to provide an output of the oscillator to one or more logics, wherein the clock distribution network is coupled to the second power supply rail.
