The output frequency and the input control voltage of the corresponding oscillating circuit ( VCO ), is the frequency of an input signal voltage function of the oscillator VCO, oscillator operating state or oscillating circuit component parameters by the input control voltage to the control, can constitute a voltage-controlled oscillator. The characteristics of output angular frequency omega 0and input control voltage UC and the relationship between the curve (Fig. 1) to represent the. In the graph, UC zero angular frequency omega0,0called the free oscillation of the angular frequency omega0,0; curve in slope at K0called control sensitivity. In communication or measuring apparatus, input control voltage for transmission or for measuring signal ( modulated signal). People usually put a voltage-controlled oscillator called FM converter, to produce a frequency modulated signal. In the automatic frequency control loop and the phase locked loop, input control voltage error signal voltage, voltage controlled oscillator is a loop in a controlled unit.
VCO voltage controlled oscillator types are LC, RC voltage-controlled oscillator and crystal voltage controlled oscillator. The voltage controlled oscillator technical requirements are: frequency stability, high control sensitivity, frequency range, frequency and voltage control in a linear relationship and is suitable for integration. Crystal oscillator frequency stability is high, but the FM range is narrow, RC voltage controlled oscillator frequency stability and low frequency range, LC VCO in between the two. In a LC oscillator, the voltage controlled variable reactance element insertion oscillation circuit is capable of forming an LC voltage controlled oscillator. The early voltage controlled variable reactance element is reactance tube, but most of the use of variable capacitance diode. Figure 2carats of type LC VCO circuit principle. In the graph, T transistor, L loop inductance, C1, C2, Cv circuit capacitance, Cv varactor diode is reverse biased exhibited capacity; C1, C2is usually much larger than Cv. When the input control voltage change of UC, Cv change, thus altering the oscillation frequency. The VCO output frequency and the input control voltage for a relationship between
The VCO output frequency and the control voltage relation formula of C0 is zero when the reverse bias voltage variable capacitance diode capacitance; phi is a varactor diode junction voltage; y is the junction capacitance change index. In order to obtain the linear control characteristic, can take various kinds of compensation measures.
RC VCO in monolithic integrated circuits commonly used in RC voltage-controlled multivibrator (see FM converter ).
