Title:
CLOCK COMPENSATION CIRCUIT, CLOCK CIRCUIT, AND MICROCONTROLLER
Document Type and Number:
WIPO Patent Application WO/2018/090650
Kind Code:
A1
Abstract:
The invention discloses a clock compensation circuit, a clock circuit, and a microcontroller. The clock compensation circuit comprises: a detection circuit used to detect a capacitance control parameter capable of affecting a clock frequency output from a clock circuit; and a control unit connected to the detection circuit, and used to adjust, according to the capacitance control parameter detected by the detection circuit, capacitance of a target capacitor, so as to change the clock frequency output from the clock circuit. The invention is utilized to resolve an issue of large fluctuation of a clock frequency output by a clock circuit in the related art.
