Title:
QUADRATURE PHASE RELAXATION OSCILLATOR USING FREQUENCY ERROR COMPENSATION LOOP
Document Type and Number:
WIPO Patent Application WO/2018/110871
Kind Code:
A1
Abstract:
The present invention relates to a technique of compensating a frequency error of a quadrature phase relaxation oscillator. The present invention generates a signal of a desired frequency by using a resistor and a capacitor that are less sensitive to process, voltage, and temperature variations, and compensates, through a feedback loop, an error in a design that arises from a mismatch of a circuit which is a characteristic of semiconductor manufacturing processes, thereby generating a signal of a desired frequency and removing noise.
