Abstract
A first capacitor is charged by a driving current. A second capacitor is charged by a driving current. A first discharging transistor discharges the first capacitor in accordance with a charged voltage of the second capacitor. A second discharging transistor discharges the second capacitor in accordance with a charged voltage of the first capacitor. The oscillation circuit generates an oscillation signal in accordance with the charged voltages of the first and second capacitors. An oscillation restarting circuit, when the first and second discharging transistors simultaneously perform discharging and thus oscillation stops, causes the discharging of the second discharging transistor to stop, and thereby, restarts the oscillation.
