Abstract
The present invention is an apparatus for efficiently providing an output frequency signal based upon an input voltage. The sampling voltage controlled oscillator of the present invention may include a voltage controlled oscillator coupled with sample and hold circuitry. The voltage controlled oscillator frequency of the sampling voltage controlled oscillator may be a lower frequency whereby the voltage controlled oscillator frequency is sampled by the sample and hold circuitry to derive a higher frequency signal. Advantageously, the overall power consumption of sampling voltage controlled oscillator may be less than conventional voltage controlled oscillators.
