Title:
ANALOG TRANSCAP DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/194336
Kind Code:
A3
Abstract:
Use: for manufacturing semiconductor structures of variable capacitance devices. The present invention describes a MOS based semiconductor variable capacitor structure, named transcap, which comprising: a first equivalent capacitance plate; a second equivalent capacitance plate; at least one control region; capacitance value between said first and second capacitance plates of said semiconductor variable capacitor is varied by varying a control voltage; wherein said control region forms a rectifying junction with said first capacitance plate, and wherein the variation of said control voltage causes a variation of the voltage drop across said rectifying junction. Technical result: allows for the decoupling of the AC signal from the DC control voltage preventing distortions and increasing the performance of the device, such as control reliability.
