Abstract:
     An oscillating circuit includes an oscillating transistor 21 in which the collector or the base is grounded in a high-frequency manner, and a bias resistor 27 connecting the emitter of the oscillating transistor 21 to a ground in a direct-current manner. In the oscillating circuit, a resonance unit 28, having maximum impedance at the oscillation frequency, is interposed between the bias resistor 27 and the ground. Then, an oscillation signal is obtained from the connection point between the bias resistor 27 and the resonance unit 28.
