Abstract
Provided is an oscillation circuit including: a first current source circuit; a second current source circuit; a resistor between the output terminal of the first current source circuit and a second power source; a first capacitor; a second capacitor; a first comparator circuit having a first input terminal to which is a voltage across the resistor is applied as a reference voltage and a second input terminal to which a voltage of the first capacitor is applied; a second comparator circuit having a first input terminal to which is the reference voltage is applied and a second input terminal to which a voltage of the second capacitor is applied; an RS latch; a first and a second switches switching a destination, of an current supplied from the second current source circuit, selected from the first and the second capacitors.
