| 摘要 |
A clock signal generation circuit includes a CR oscillator circuit having a capacitor, a resistor, and an amplifier circuit, and a voltage generation circuit adapted to generate a power supply voltage, and then supply the CR oscillator circuit 170 with the power supply voltage VDOS. An oscillation frequency of the CR oscillator circuit in a case in which a power supply voltage VDDL is a fixed voltage has a positive temperature characteristic. The voltage generation circuit generates the power supply voltage VDOS having a negative temperature characteristic based on a work function difference between transistors, and then supplies the power supply voltage VDOS as a power of the amplifier circuit of the CR oscillator circuit. |
