Abstract
A circuit for modifying a resonant frequency of a receiver for radio frequency signals. The receiver includes an inductor connected in parallel with a capacitor. The circuit includes a switch having an additional capacitor connected between two MOS transistors, the switch being connected in parallel with the receiver to add capacitance based on a control of the MOS transistors.
