Abstract
A charge sharing circuit for generating a calibration voltage. The circuit comprises a calibration capacitor for providing at an upper terminal of the calibration capacitor the calibration voltage. The circuit further comprises a series connection of a plurality of N switches, wherein N is an integer>2, and a plurality of at least N−1 switching capacitors. Each switching capacitor is coupled to one connecting node connecting two of the N switches. One side of the series connection of the plurality of N switches is coupled to the upper terminal of the calibration capacitor and the other side of the series connection of the N switches is coupled to a fixed voltage. The circuit is configured to transmit at least two clock signals to selectively drive at least two distinct subsets of the switches. There is further provided a corresponding method and a corresponding design structure.
