Abstract
An oscillator control system that includes an oscillator structure; a phase error detector configured to generate a phase error signal based on a delayed event time signal and delayed reference signal; an analog signal path coupled between the oscillator structure and the phase error detector, the analog signal path configured to receive an event time signal and produce the delayed event time signal; a control circuit configured to generate a reference signal; a programmable delay circuit configured to receive the reference signal and induce a programmable delay on the reference signal thereby generating the delayed reference signal; and an analog delay measurement circuit configured to inject a test signal into the analog signal path, receive a delayed test signal from the analog signal path, measure an analog delay of the delayed test signal, and generate a configuration signal configured to adjust the programmable delay according to the measured analog delay.
