Abstract: A resonator of a VCO includes a fine tuning main varactor circuit, an auxiliary varactor circuit, and a coarse tuning capacitor bank circuit coupled in parallel with an inductance. The main varactor circuit includes a plurality of circuit portions that can be separately disabled. Within each circuit portion is a multiplexing circuit that supplies a selectable one of either a fine tuning control signal (FTAVCS) or a temperature compensation control signal (TCAVCS) onto a varactor control node within the circuit portion. If the circuit portion is enabled then the FTAVCS is supplied onto the control node so that the circuit portion is used for fine tuning. If the circuit portion is disabled then the TCAVCS is supplied onto the control node so that the circuit portion is used to combat VCO frequency drift as a function of temperature. How the voltage of the TCAVCS varies with temperature is digitally programmable.

Abstract: 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.

Abstract: An RF oscillator (10) is disclosed that can be tuned to operate over a wide range of frequencies while maintaining advantageous bias conditions. The oscillator includes circuitry (32) that adjusts an oscillator bias signal in response to changes in oscillator frequency and/or ambient temperature, and does so without resort to using the same signal for both bias and frequency control. By so doing, both the frequency range and temperature range of an oscillator can be extended, while simultaneously improving the oscillator's performance.
