Abstract
A voltage-controlled capacitor is configured in such a way that it contains two varactors connected in parallel. The varactors are connected in such a way that a capacitance is controlled by differential signals. This layout results in a voltage-controlled capacitor that has an optimally low sensitivity to interference.
Claims4
A voltage-controlled capacitor, comprising:
- two varactors connected in parallel and having a capacitance, said two varactors being connected for controlling the capacitance with difference signals, and said two varactors including a first varactor having an nMOS layer sequence and a second varactor having a pMOS layer sequence.
Dependencies are inferred from the claim text.
