Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A circuit comprising:
a modulation circuit;
a reset circuit;
an LC tank, the reset circuit coupled to the LC tank;
a voltage multiplier, having an input, the voltage multiplier coupled to a capacitor of the LC tank; and
a time-varying voltage source coupled to the input of the voltage multiplier,
wherein the voltage multiplier, the reset circuit, and a capacitor C of the LC tank are in series, the series combination of the voltage multiplier, the reset circuit, and the capacitor in parallel with an inductor L of the LC tank, the voltage multiplier configured to receive a periodic modulating signal and the reset circuit coupled to the voltage multiplier and the LC tank based on a periodic reset signal, the modulation circuit configured to modulate an effective inductance or capacitance when connected to the LC tank creating a modulated LC tank.
