Continuous-time circuit and method for capacitance equalization based on electrically tunable voltage pre-distortion of a C-V characteristic
Abstract:
A capacitance compensation circuit includes a plurality of switches having a first node coupled to an input terminal, a plurality of capacitors each coupled to a respective second node of the plurality of switches, and an adjustment circuit for providing a plurality of adjustable bias levels to a plurality of switch control nodes to precisely compensate for linear and parabolic voltage dependent components of an input or other capacitor. Two such circuits can be used with a single input terminal to compensate for both increasing and decreasing voltage dependent characteristics of a target capacitor.
