Abstract
A programmable voltage-controlled oscillator includes a ring oscillator having a number of selectable delay stages, and a resistor value detection circuit configurable for coupling to an external resistor. The resistor value detection circuit includes at least one internal resistor and is operative to generate, based at least in part on a value of the external resistor, an output signal indicative of a value of the internal resistor. The output signal is utilizable in controlling an oscillation frequency of the ring oscillator based at least in part on selection of one or more of the selectable delay stages. The voltage-controlled oscillator may be utilized in a phase-locked loop of clock recovery circuit in an integrated circuit, and in numerous other applications.
