ABSTRACT:
An oscillating section110comprised of feedback inverter INV1and a feedback resistor R2, and a waveform shaping section120including a Schmitt circuit S1of which transistors P3and N3respectively receive, as gate control signals, signals Gp3and Gn3generated by a stable-oscillation signal A1and logic elements AND1, OR1and INV3, respectively, and the supply of power to the waveform shaping section120is performed through a low pass filter111comprised of a resistor R1and a capacitor C1and thus a high potential power source VDD is supplied to the waveform shaping section120as a high potential power source VDDX.
