    摘要： A VCO (1) includes two variable impedance circuits that independently control oscillation frequency of the VCO (1) based on an input control voltage. A frequency-correction-voltage generating unit (3) outputs a voltage for compensating for a temperature drift of the oscillation frequency according to an ambient temperature of a circuit, for a first variable impedance circuit. An FM-modulation-voltage generating unit (2) outputs a modulation voltage containing a temperature-independent constant DC component and a predetermined AC component, for a second variable impedance circuit, under a temperature drift compensation condition set by the frequency-correction-voltage generating unit (3).

    摘要： A modulation-signal generating circuit obtains a highly linear FM modulation wave within a legal frequency range. The modulation-signal generating circuit simplifies temperature data of a modulation correction voltage to obtain the FM modulation wave high linearity. The modulation-signal generating circuit includes a temperature monitoring unit 4 that detects a casing temperature of the circuit, a voltage control oscillator 1 having two variable impedance circuits that independently control oscillation frequency based on an input control voltage, a frequency-correction-voltage generating unit 3 that outputs a voltage for compensating for a temperature drift of an oscillation frequency according to the casing temperature detected by the temperature monitoring unit 4, to one of the variable impedance circuits, and an FM-modulation-voltage generating unit 2 that outputs a modulation voltage containing a constant DC component not depending on temperature and a predetermined AC component, to the other variable impedance circuit, under a temperature drift compensation condition of the frequency-correction-voltage generating unit 3.

    摘要： A voltage controlled oscillator based on the Colpitt's design is provided. An inductor (Lc) is provided in parallel to one (Cs) of a pair of series connected capacitors (Cs, Cd). The present of the inductor (Lc) modifies the impedance ratio of the pair of series connected capacitors (Cs, Cd) by introducing a frequency dependence. This frequency dependence mitigates frequency dependent losses in a tuned circuit (Lr, Ct) in the voltage controlled oscillator. The invention provides an enhanced output signal over the frequency range of operation of the voltage controlled oscillator. The invention also improves the modulation of the voltage controlled oscillator's output signal which can be achieved by a separate modulation circuit (Cm, Rm, Vm).
