Abstract

A charging and discharging circuit of a triangular wave oscillation circuit includes an inverter circuit; a discharging reference potential generating circuit; a first NMOS transistor having a drain connected with a connection point between a first current source circuit and the capacitor, and a gate connected with the discharging reference potential generated by the discharging reference potential generating circuit; a second NMOS transistor having a gate inputted with the switching signal through the inverter circuit, a drain connected with the gate of the first NMOS transistor, and a source connected with a source of the first NMOS transistor; and a third NMOS transistor having a gate inputted with the switching signal, a drain connected with a connection point between the source of the first NMOS transistor and the source of the second NMOS transistor, and a source grounded.
