Abstract
A switched-capacitor circuit includes a sampling capacitor array, a control circuit, and a charge-transfer circuit. The sampling capacitor array is configured to sample an input voltage in a sampling phase. The control circuit is configured to determine magnitude of a preset voltage according to the input voltage, and configured to adjust the input voltage sampled by the sampling capacitor array in a preset phase according to magnitude of the input voltage to generate an adjusted voltage. The charge-transfer circuit is configured to amplify the adjusted voltage in a charge-transfer phase to generate an output voltage at an output terminal, and configured to provide the preset voltage to the output terminal in the preset phase.
