OSCILLATOR

WIPO Patent Application WO/2012/056600

A1

Provided is an oscillator capable of reliably operating by acquiring necessary negative resistance with less current. The present invention is provided with: a plurality of oscillation units (10 and 20) which are provided with resonant circuits (13 and 23) having capacitance elements (134 and 234) and inductors (133 and 233) which are disposed mutually in parallel, negative resistance generators (14 and 24) having a plurality of transistors disposed so that negative resistance which counteracts the loss from the resonant circuits (13 and 23) is generated, first bias terminals (15 and 25), and second bias terminals (16 and 26); and a coupling unit (30A) for electrically coupling the plurality of oscillation units (10 and 20) so that the resonant circuits (13 and 23) are each coupled to one another in parallel equivalently; wherein the plurality of oscillation units (10 and 20) are serially connected to one another in a first bias terminal (25) and a second bias terminal (16), respectively, thereof for each oscillation unit, and a plurality of transistors (143, 144, 243, and 244) in the plurality of oscillation units (10 and 20) are configured with mutually identical conductivity types.
