Abstract
A switched-capacitor circuit includes a sampling capacitor array, a charge-transfer circuit and a control circuit. The sampling capacitor array is configured to sample an input voltage in a sampling phase. The charge transfer circuit includes a first current source and a second current source having different current-voltage characteristics, in which the first current source and the second current source are coupled with an output terminal. The control circuit is configured to adjust, in a preset phase, a sampling result of the sampling capacitor array according to the input voltage in order to generate an adjusted voltage. The control circuit is further configured to enable one of the first current source and the second current source in a charge-transfer phase, according to the input voltage, so that the charge-transfer circuit amplifies the adjusted voltage in the charge-transfer phase to generate an output voltage at the output terminal.
