Title:
RC OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2021/000064
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application is an RC oscillator. The RC oscillator may use a first amplifier and a second amplifier to amplify the difference between a first voltage and a second voltage. The first amplifier may comprise a first amplifying circuit and a second amplifying circuit. The first amplifying circuit and the second amplifying circuit may multiplex the same voltage current conversion circuit. The RC oscillator disclosed in embodiments of the present application may not only prevent the first amplifier from introducing noise, but may also reduce noise at the interior of the RC oscillator, thereby reducing the jitter of a clock signal.
