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.
Claims19
A circuitry for enabling synchronized chopping for ring oscillators, the circuitry comprising:
- 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.
A method of operating a circuitry for enabling synchronized chopping for ring oscillators, wherein the circuitry comprises:
- a differentially arranged pair of ring oscillators;
- a chopping logic;
- and
- a control logic;
- and
- wherein the method comprises:
- stopping, by the control logic, each ring oscillator in a predefined state;
- enabling, by the control logic, the chopping logic to perform chopping operation after both ring oscillators are stopped;
- performing, by the chopping logic, the chopping operation for the ring oscillators;
- and
- restarting, by the control logic, both ring oscillators after the chopping operation is completed.
