A semiconductor integrated circuit capable of achieving drain current and transconductance required for driving an analog switch even after lowering a supply voltage. The circuit includes a boosting section for generating a voltage equal to or greater than the supply voltage, and an output section for outputting a voltage generated by the boosting section according to an input signal. The boosting section includes a capacitor for storing electric charges equivalent to a difference between the voltage equal to or greater than the supply voltage and the supply voltage. Accordingly, a voltage equal to or greater than the supply voltage can be applied to the analog switch requiring large transconductance. Therefore, even if the supply voltage is decreased, a percentage of a reduction of the transconductance can be relatively low, whereby a voltage of electronic equipment can be lowered.
