Abstract
PURPOSE:To obtain wide band oscillation frequency characteristics in the high frequency region, by providing a voltage contol variable impedance element in a part of an amplifier to change the phase characteristics of the amplifier constituting an oscillator. CONSTITUTION:An oscillator consists of a resonance circuit 28 including a voltage control variable impedance element 11, an oscillating amplification block 29 including a transistor, a circuit block 30 which changes the input impedance by a control voltage, and an oscillation output terminal 31. The control voltage is applied to the voltage control variable impedance element 11 as well as the circuit block 30 simultaneously from a terminal 33 through a bias resistance 32.
