VOLTAGE CONTROLLED OSCILLATOR |
摘要 |
This invention relates to an integrated circuit voltage controlled oscillator comprising a resonator circuit; an amplifier circuit connected to said resonator circuit; a first input terminal; and anoutput terminal. The amplifier and resonator circuits are arranged as a differential circuit having a first and as econd branch. The resonator circuit comprises a variable capacitance circuit and an inductance circuit connecte to an interacting with said variable capacitance circuit. The input terminal is provided at a first balanced input node of said variable capacitance circuit between said first and second branches. The capacitance of at least a part of said variable capacitance circuit, and the frequency of an output signal at said input terminal. The capacitance circuit comprises a first pair of varaible capacitance units being DC isolated and being connected to said balanced input node and to said first and second branches respectively. |
