ABSTRACT:
An amplifier circuit includes a current source that is connected between a power supply voltage and an output node and that is turned on when a switching control signal takes a first value and is turned off when the switching control signal takes a second value; a grounded voltage control current source whose amount of current is controlled by an input voltage; a cascode transistor connected between the voltage control current source and the output node; a boost amplifier connected between a gate electrode and a source electrode of the cascode transistor; and a switch that is connected between an output node of the boost amplifier and a bias voltage and that is turned on for a predetermined period of time when a value of the switching control signal is switched from the second value to the first value, to forcefully rise the boost amplifier.
