Classification: CPC H | IPC H

Claim 13:
14. The device of claim 12, further comprising:
an analog differential tuning control system configured to generate the differential control signal as an analog differential control voltage that is applied to the differential control terminals of the variable capacitor device to adjust a capacitance of the tank circuit by changing an impedance of the first and second transistors; and
a calibration system configured to generate first and second reference voltages that are applied to the first and second tuning terminals, respectively, of the variable capacitor device to adjust at least one of (i) a capacitance-to-differential voltage transfer curve of the variable capacitor device and (ii) a ratio of a differential mode gain to a common mode gain of the variable capacitor device.
