Abstract
An integrated circuit (IC) includes a ring oscillator. One may tune the ring oscillator by controlling a power supply of the ring oscillator. One may further tune ring oscillator by varying a capacitance of at least one varactor. Using the tuning techniques, one may tune the output frequency of the ring oscillator to a desired frequency.
