摘要： A voltage controlled oscillator enables controlling the MOS transistor threshold voltage independently of the temperature compensation control signal and external voltage frequency control signal. The voltage controlled oscillator has a crystal oscillator and a load capacitance is parallel connected to a crystal oscillator. The load capacitance includes a first MOS transistor comprising a gate terminal and a source/drain terminal formed by shorting the source and drain, and a second MOS transistor comprising a gate terminal and a source/drain terminal formed by shorting the source and drain. First and second control signal generating circuits supply respective control signals to the source/drain terminals and gate terminals of the first and second MOS transistors.

摘要： A first order function generation circuit receives a signal from a temperature sensor circuit, and generates a first order function control signal V1 that is affected by the ambient temperature. A fourth order and fifth order approximation function generation circuit receives signals from the temperature sensor circuit and from the third order approximation function generation circuit, and generates a fourth and fifth order approximation function control signal V45 that is affected by the ambient temperature. A peak change point adjustment circuit outputs a signal to adjust the value of a peak change point temperature Ti for the third order approximation function generation circuit, the first order generation function circuit and the fourth order and fifth order approximation function generation circuit. A temperature compensation circuit adds together control signals V0, V1, V3 and V5, and outputs the resultant signal Vc.
