  • Publication number: 20250085738
    Abstract: A clock generating circuit includes a buffer circuit and a phase compensating circuit. The buffer circuit buffers an input clock signal to generate an output clock signal. The phase compensating circuit detects a noise in a power voltage and adjusts, according to the noise of the power voltage, a voltage level of the input clock signal to compensate for a phase change of the output clock signal due to the noise of the power voltage.
