Abstract
It is an object of the present invention to shorten a time required until phases of output signals being output from two output terminals are inverted respectively from a start time of an oscillation in a differential oscillation apparatus. In a differential oscillation apparatus according to the present invention which includes a differential oscillator portionhaving an external input terminal at a terminal of one transistorand a switch circuit, a first control signal generation circuitfor generating a first control signal to control an oscillation start and an oscillation stop of the differential oscillator portion, and a second control signal generation circuitfor generating a second control signal input into the terminal of one transistorof the differential oscillator portion, when a phase relationship between collector currents flowing through two transistorsis decided by the second control signal, output signals being output from two output terminals are opposite in phase from a start time of an oscillation.
