Abstract
Systems and methods of low power clocking of sleep mode radios are disclosed herein. In an example embodiment, a crystal oscillator is purposefully mistuned to achieve lower power consumption, and then synchronized using a high frequency crystal oscillator. In an alternative embodiment, the input offset voltages of the comparator in an RC oscillator are cancelled, which allows low power operation and high accuracy performance when tuned to the high frequency crystal. A lower power comparator may be used with higher input offset voltages but still achieve higher accuracy. The RC circuit is switched back and forth on opposite phases of the output, cancelling the offset voltage on the inputs of the comparator.
