Abstract:
A first tuning circuit tunes an oscillation frequency by changing, based on a first control signal, capacitance values of variable capacitive elements connected in parallel to an inductor. A second tuning circuit switches capacitive elements in and out of parallel connection with the inductor by turning on and off a transistor based on a second control signal, to thereby tune the oscillation frequency. A switching circuit includes n-channel transistors whose drains are connected via resistor elements to the source or drain of the transistor and a power and whose sources are grounded, and changes a bias voltage of the second tuning circuit by turning on and off the n-channel transistors based on the second control signal.

Claim (Index 1):
A voltage controlled oscillator comprising:\n an inductor; a first tuning circuit configured to include a variable capacitive element connected in parallel to the inductor, and receive a first control signal and tune an oscillation frequency by changing, based on the first control signal, a capacitance value of the variable capacitive element; a second tuning circuit configured to include a capacitive element and a first transistor whose first source or first drain is connected to the capacitive element, receive a second control signal and switch the capacitive element in and out of parallel connection with the inductor by turning on and off the first transistor based on the second control signal, to tune the oscillation frequency; and a switching circuit configured to include at least one n-channel second transistor whose second drain is connected via a resistor element to the first source or the first drain and a power and whose second source is grounded, and change a bias voltage of the second tuning circuit by turning on and off the at least one n-channel second transistor based on the second control signal.
