Abstract
A variable capacitor circuit is disclosed. The variable capacitor circuit includes a plurality of MOS capacitors, each MOS capacitor being implemented by a MOS transistor with the gate terminal connected to a first voltage signal and with the drain terminal shorted with the source terminal and connected to a second voltage signal, said MOS capacitors being connected in parallel through the gate terminal connected to the first voltage signal, and being operated in a cut-off region in which the equivalent capacitance of each MOS capacitor remains substantially constant for variations of the first voltage signal.
