Abstract
Provided is an amplifier that includes a first transistor including a gate terminal to which an applied input signal is input, where a current depending on the applied input signal flows through the first transistor. A gate terminal of a second transistor is connected to a load section, and a current depending on a change in a voltage of the drain terminal of the first transistor flows through the second transistor. A source terminal of the first transistor and a drain terminal of the second transistor are connected in common to a first resistance, and the current from the first transistor and the current from the second transistor flow through the first resistance. A third transistor supplies a current approximately equal to the current of the second transistor. The current supplied by the third transistor is output from an output end.
