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