    摘要: Oscillator calibration circuits and wireless transmitters including oscillator calibration circuits. An oscillator calibration circuit includes a first frequency locking circuit (FLC) coupled to a first oscillator, wherein the first FLC calibrates the frequency of the first oscillator using an over-the-air reference signal, wherein the first FLC calibrates the first oscillator prior to a data transmission session and remains free running during the data transmission session.
