Abstract
An auto trimming oscillator includes a Successive Approximation Register (SAR), a frequency detector and an n-bit comparator. The SAR is used to iteratively trim the oscillator output clock frequency based on a difference between a reference clock frequency and the oscillator output clock frequency. The oscillator is trimmed to deliver a clock frequency which is a closest match to the reference clock frequency.
