Abstract
Described herein is a circuitry for enabling synchronized chopping for ring oscillators. The circuitry may include a differentially arranged pair of ring oscillators; a chopping logic configured to perform a chopping operation for the ring oscillators; and a control logic configured to: stop each ring oscillator in a predefined state; enable the chopping logic to perform the chopping operation after both ring oscillators are stopped; and restart both ring oscillators after the chopping operation is completed.
