Abstract
A mobile communication device is provided that has a transceiver including a voltage controlled oscillator (VCO) and a calibration circuit for calibrating the VCO. The calibration circuit includes a logic block configured to estimate a calibration value for a tuning of the VCO to a desired frequency, and an asynchronous counter configured to execute a counting sequence to identify a frequency of the VCO after the tuning of the VCO using the calibration value, where the calibration circuit is configured to determine a tuned calibration value for producing the desired frequency from the counting sequence.
