Abstract
A wireless communication device can include an oscillator circuit. The oscillator circuit can include an oscillator and measurement circuitry coupled to the oscillator. The measurement circuitry can receive an output signal of the oscillator and measure oscillator error by comparing the output signal of the oscillator to a nominal frequency for an amount of time. The oscillator circuit can further include adjustment circuitry to adjust an oscillator frequency of the oscillator based on the measured oscillator error.
