摘要:
A disclosed oscillation circuit includes a constant-voltage generation circuit, an oscillation generation circuit configured to generate an oscillation output, an output circuit including a plurality of parallelly arranged MOSFET circuits, to which a constant voltage generated by the constant-voltage generation circuit is supplied as a supply voltage, output points of the plurality of MOSFET circuits being mutually connected, and a drive circuit configured to drive a selected MOSFET circuit selected in response to a selection input among the plurality of MOSFET circuits by the oscillation output, wherein an output from an unselected MOSFET circuit among the plurality of MOSFET circuits other than the selected MOSFET circuits has a high impedance.
