An oscillator circuit includes a capacitor, a first constant current source electrically couplable to an end of the capacitor, a second constant current source electrically couplable to the end of the capacitor, a control circuit coupled to the end of the capacitor, a first reference potential, and a second reference potential to switch, in response to a comparison of a potential at the end of the capacitor with the first and second reference potentials, between a first operation to charge the capacitor by electrically coupling the first constant current source to the end of the capacitor and a second operation to discharge the capacitor by electrically coupling the second constant current source to the end of the capacitor, and a circuit configured to have an output signal thereof exhibiting a signal transition in response to timing at which the switching occurs between the first operation and the second operation.
