Abstract:
1. A differential oscillation apparatus, comprising: a differential oscillator portion which includes a first transistor and a second transistor, one terminals of which are connected in common and other two terminals of which are connected to cross each other and the one terminals of which connected in common are connected to a current source; two output terminals; and an external input terminal which is provided to a terminal of either of the first transistor and the second transistor, wherein a first control signal for controlling a start and an end of an operation of the current source is supplied to a terminal of the current source; wherein a second control signal for controlling a voltage between terminals of the first transistor and the second transistor is supplied to the external input terminal; and wherein the second control signal is a rectangular wave whose pulse width is half of an oscillating period.
