Abstract
A capacitor array includes a plurality of capacitor components each having a first node and a second node, and first nodes of the capacitor components are coupled to each other. A calibration method for the capacitor array utilizes a calibration capacitor component to couple the first nodes. Then, the calibration method determines a capacitance indication value regarding the specific capacitor component by coupling different references voltage to a second node of the specific capacitor component and coupling different test voltages to a second node of the calibration capacitor component. Accordingly, the calibration method calibrates the capacitance mismatches of the capacitor array in the digital domain.
