Abstract: In a microwave voltage controlled oscillator, a negative resistance circuit (5) having an output terminal is connected to a first terminal of a strip shaped resonator (1). The anode of a variable capacitance diode (2) is connected to a second terminal of the strip shaped resonator via a capacitor (1').The cathode of the variable capacitance diode is grounded. One terminal of a high impedance strip shaped line (3) is connected to the anode of the variable capacitance diode (2). The other terminal of the strip shaped line is grounded via a capacitor (4). The capacitor (4) has sufficiently low impedance at an oscillation frequency. The microwave VCO may be applied to an automobile radar.

Abstract: PROBLEM TO BE SOLVED: To multiply the output frequency of an oscillator by a circuit whose multiplication loss is small, and whose scale is small as a result.
SOLUTION: This electronic circuit device is provided with: a negative resistance circuit (15) including a first transistor (10) whose control terminal (G1) is connected to a resonator (30) and a second transistor (20) whose control terminal (G2) is connected to an output terminal (D1) of the first transistor (10), and which is serially connected via a path (25) different from the control terminal (G2) between a DC bias terminal (Vdd) and the output terminal (D1) of the first transistor (10).
