| abstract |
A high-accuracy clock signal is generated even when the setting of the clock frequency is changed or even when the power supply or temperature varies. A frequency / voltage conversion circuit 13 includes a switch unit including switches SW1 and SW2, capacitance elements C and C10 to C13, and switches CSW0 to CSW3. Capacitance elements C10 to C13 are configured with different absolute values of capacitance, and are provided to cover the frequency range intended by the designer. For example, the capacitance values C11 to C13 weighted by 2 are selected by the switches CSW0 to CSW3 based on the 4-bit frequency adjustment control signals SELC0 to SELC3, Switch.
