Abstract
Circuitry includes an amplifier circuit having a first transistor, an inductor, and a second transistor, and a distortion compensation circuit having a third transistor, a forth transistor, and a first capacitor. The first transistor is applied input signal. The inductor is connected to a source of the first transistor and grounded on another side. The second transistor has a source connected to a drain of the first transistor, a grounded gate and a drain connected to a power supply, and outputs an amplified signal. The third transistor has a drain and a gate connected to the drain, and is connected to the power supply on the drain. The fourth transistor has a drain and a gate connected to a source of the third transistor, and is grounded on a source. The first capacitor connects nodes between the drain of the first transistor and the source of the third transistor.
