Embodiments of this application disclose an RC oscillator that amplifies a difference between a first voltage and a second voltage by using a first amplifier and a second amplifier. The first amplifier may include a first amplification circuit and a second amplification circuit. The first amplification circuit and the second amplification circuit may share a same voltage-current conversion circuit. The RC oscillator disclosed in the embodiments of this application not only avoids noise introduced by the first amplifier, but also reduces internal noise of the RC oscillator and a jitter of a clock signal.
