Abstract
The oscillator circuit comprises an oscillator including an oscillating transistor through which an oscillating current flows; a first mirror transistor where the source/drain of which is grounded and the drain/source of which is connected to the oscillating transistor in series; a first reference transistor where the source/drain of which is grounded and the drain/source and the gate of which are connected in common to the gate of the first mirror transistor; a second mirror transistor where the source of which is connected to a power line and the drain/source of which is connected to the drain/source of the first reference transistor; and a second reference transistor where the source/drain of which is connected to the power line, the drain/source and the gate of which are connected in common to the gate of the second mirror transistor and the drain/source of which is connected to an external terminal to which an external resistor is connected. The oscillating current is adjusted by adjusting a current flow through the external resistor and the second reference transistor.
