    Abstract: Certain aspects of the present disclosure provide a semiconductor variable capacitor. The semiconductor variable capacitor generally includes a semiconductor region, an insulative layer disposed above the semiconductor region, and a first non-insulative region disposed above the insulative layer. In certain aspects, a second non-insulative region is disposed adjacent to the semiconductor region, and a control region is disposed adjacent to the semiconductor region such that a capacitance between the first non-insulative region and the second non-insulative region is configured to be adjusted by varying a control voltage applied to the control region. In certain aspects, the first non-insulative region is disposed above a first portion of the semiconductor region and a second portion of the semiconductor region, and the first portion and the second portion of the semiconductor region are disposed adjacent to a first side and a second side, respectively, of the control region or the second non-insulative region.
