Abstract
A comparator-based switched-capacitor circuit (SC circuit) has a first output terminal and a second output terminal, which output a first output signal and a second output signal, respectively. The comparator-based SC circuit includes a switch-capacitor network, a first current source, a second current source, and a compensation circuit. The first current source is coupled to the switch-capacitor network and the first output terminal. The second current source is coupled to the switch-capacitor network and the second output terminal. The compensation circuit is coupled to the first output terminal and the second output terminal and configured to generate a first and second voltage differences corresponding respectively to the first and second output signals and apply the first and second voltage differences to the second and first output terminals, respectively.
