Hybrid namp;plus; and pamp;plus; gate-doped voltage variable capacitors to improve linear tuning range in voltage controlled oscillators

摘要

A method for operating a wide band voltage controlled oscillator comprises using a control voltage to tune the capacitance of at least one hybrid n+ and p+ gate-doped voltage variable capacitor of the wide band voltage controlled oscillator. A hybrid voltage variable capacitor includes a substrate, a well adjacent to the substrate, a first and second set of contact elements adjacent to the well, a first channel layer adjacent to the well and bound by the first set of contact elements, a first insulating layer adjacent to the first channel layer, a first electrode adjacent to the first insulating layer, a second channel layer adjacent to the well and bound by the second set of contact elements, a second insulating layer adjacent to the second channel layer, and a second electrode adjacent to the second insulating layer.
