(54) Title: LAYOUT TECHNIQUES FOR TRANSCAP AREA OPTIMIZATION (57) : Certain aspects of the present disclosure provide a 300 semiconductor variable capacitor. The semiconductor variable capac- itor generally includes a semiconductor region, an insulative layer disposed above the semiconductor region, and a first noninsulative region disposed above the insulative layer. In certain aspects, a sec- ond noninsulative 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 302 varying a control voltage applied to the control region. In certain as- pects, the first non-insulative region is disposed above a first portion of the semiconductor region and a second portion of the semiconduc- tor region, and the first portion and the second portion of the semi- 6 conductor region are disposed adjacent to a first side and a second side, respectively, of the control region or the second non-insulative region.
