Abstract
An amplifier includes a variable shunt circuit including a first transistor group and a second transistor group. The first transistor group includes at least one transistor including a first terminal connected directly or indirectly to a voltage-current conversion circuit, a second terminal connected directly or indirectly to a load, and a third terminal connected directly or indirectly to a control circuit. The second transistor group includes at least one transistor including a first terminal connected directly or indirectly to the voltage-current conversion circuit, a second terminal connected directly or indirectly to a power source or a ground, and a third terminal connected directly or indirectly to the control circuit. The amplifier is configured to amplify the input signal under exclusive control from the control circuit on a pair of the at least one transistor of the first transistor group and the at least one transistor of the second transistor group.
