Abstract
An oscillator calibration circuit is provided. The oscillator calibration circuit includes a signal frequency detector for producing a reference signal from a received over-the-air signal detecting a frequency of the over-the-air signal; and a first frequency locking circuit (FLC) coupled to the signal frequency detector and to a first oscillator, wherein the first FLC calibrates the frequency of the first oscillator using the reference signal to a radio frequency (RF) carrier frequency, wherein the reference signal is utilized for calibrating the first oscillator based on the frequency of the detected over-the-air signal.
