Abstract
A capacitor circuit includes a first capacitor bank and a second capacitor bank. The first capacitor bank includes p switch-capacitor circuits connected to each other in parallel, where p is a natural number of 2 or more, wherein at least two switch-capacitor circuits among the p switch-capacitor circuits have mutually different capacitance values based on a first weight. The second capacitor bank includes q switch-capacitor circuits connected to each other in parallel, where q is a natural number greater than p, wherein at least two of the q switch-capacitor circuits have mutually different capacitance values based on a second weight different from the first weight.
