Abstract
An oscillation control apparatus is provided with: an oscillating unit for oscillating an oscillating element; an output amplifying circuit having two pieces of same types of transistors series-connected to each other, for outputting a signal from a junction point between the two transistors in response to an oscillation signal outputted from the oscillating unit; a bias unit for generating two DC bias voltages having different levels from each other, which are applied to either respective gates or respective bases of the two transistors; a constant voltage power supply unit for applying a constant voltage to the oscillating unit; and an inverter unit provided between the oscillating unit and any one of either the gates or the bases of the two transistors, for inverting a phase of the oscillation signal outputted from the oscillating unit. Both the oscillation signal outputted from the oscillating unit and one of the two bias voltages are applied to either the gate or the base of one of the two transistors; and both an oscillation signal outputted from the oscillating unit and whose phase has been inverted by the inverting unit and the other bias voltage of the two bias voltages ar…
