Abstract:
A temperature compensation circuit includes: a sensing circuit arranged to sense a temperature to generate a sensing signal; an operational circuit arranged to sample the sensing signal to generate a sample signal during a first phase, and arranged to generate an output signal according to the sensing signal and the sample signal during a second phase; and a capacitive circuit arranged to provide a capacitance adjusted by the output signal.
