ABSTRACT:
A tunable ring oscillator, in accordance with the teachings described herein, may include one or more delay circuits having a coarse tuning circuitry and a fine tuning circuitry. The coarse tuning circuitry may be used to set one of a minimum time delay or a maximum time delay as a function of a coarse tuning input. The fine tuning circuitry may be used to adjust between the minimum time delay and the maximum time delay as a function of a fine tuning input.
