PROBLEM TO BE SOLVED: To provide an oscillator which can prevent an increase of a mounting area and a deterioration of a CN characteristic with a broadband oscillation frequency bandwidth. SOLUTION: A frequency setting portion sets an oscillation frequency based on a resonance frequency between a primary side inductances L1, L2 and capacities VC1 and C1. Oscillation portions Tr1 and Tr2 are oscillated based on a frequency set by the frequency setting portion. A mutual inductance M is generated for the primary side inductances L1 and L4, and control circuits L3, L4, Tr3, and Tr4 for varying the oscillation frequency are provided. COPYRIGHT: (C)2004,JPO
