【正文】 s frequency stability is low and wide range of frequency modulation, the RC voltagecontrolled oscillator in the monolithic integrated circuit is monly used in RC voltage controlled multivibratorvoltage controlled crystal oscillatorIn a quartz crystal oscillator frequency stabilization, the varactor diode and concatenated quartz crystal phase, can form a voltage controlled crystal oscillator. In order to expand the range of frequency modulation, available AT cut quartz crystal and access the base frequency of quartz crystal, the circuit can also by broadening the scope of the FM transformation network.At microwave frequencies, with reflector voltage control reflex klystron oscillator frequency with the anode voltage control frequency magnetron oscillator and so on also belong to the nature of the voltagecontrolled oscillator. Voltagecontrolled oscillator application range is very wide. Integration is an important development direction. Quartz crystal voltagecontrolled oscillator frequency stability and frequency modulation in the contradiction between range and needs to be solved. Along with the development of the deep space munication, will need internal noise level very low voltage controlled oscillator.。s easy to start up. In addition, the change of resonance loop capacitor, it can conveniently adjust the oscillation frequency, due to the feedback signal from the pressure drop on both ends of the inductance, the inductance of high order harmonic presents high impedance, so can39。s frequency stability is low and wide range of frequency modulation, in between the two LC voltagecontrolled oscillator.Voltage control in any LC oscillator in a LC oscillator circuit are the voltage controlled va
