A tunable ring oscillator having a one or more delay circuits having a coarse tuning circuitry and a fine tuning circuitry. The coarse tuning circuitry is used to set one of a minimum time delay or a maximum time delay as function of a coarse tuning input. The fine tuning circuitry is used to adjust between the minimum time delay and the maximum time delay as a function of a fine tuning input. |
