Calibration of a BST capacitor control circuit
Abstract:
A circuit for controlling a capacitor having a capacitance settable by biasing, including at least one terminal for receiving a digital set point value depending on the value desired for the capacitance, a circuit for determining a drift of the capacitance with respect to a nominal value, and a circuit of application of a correction to said digital set point value, depending on the determined drift.
