Claims
- 1. A voltage-controlled capacitor, comprising:
two varactors connected in parallel and having a capacitance, said two varactors connected for controlling the capacitance with difference signals.
- 2. The voltage-controlled capacitor according to claim 1, wherein the capacitance is controlled by the difference signals received between said two varactors.
- 3. The voltage-controlled capacitor according to claim 1, wherein said two varactors include a first varactor having an nMOS layer sequence and a second varactor having a pMOS layer sequence.
- 4. The voltage-controlled capacitor according to claim 3, wherein said two varactors are formed from CMOS circuitry.
- 5. The voltage-controlled capacitor according to claim 3, wherein said two varactors are formed from BiCMOS circuitry.
