Abstract

A highly linear, variable capacitor array constructed from multiple cells. Each cell includes a pair of passive, capacitor components connected in anti-parallel. The capacitor components may be Metal Oxide Semiconductor (MOS) capacitors. A control circuit applies bias voltages to bias voltage terminals associated with each capacitor component, to thereby control the overall capacitance of the array.
