摘要
A power amplifier (amp) is disclosed. This power amp can include a first transistor configured in the common source (CS) amplification mode, wherein the gate terminal of the first transistor is used as the input port of the power amp; and a second transistor configured in the common gate (CG) amplification mode, wherein the drain terminal of the second transistor is used as the output port of the power amp. The power amp also includes a first inductive component coupled between the drain terminal of the first transistor and the ground to increase the impedance between the drain terminal of the first transistor and the ground, thereby increasing an output power at the output port. The power amp additionally includes a second inductive component coupled between the drain terminal of the first transistor and the source terminal of the second transistor to increase the conductance in the output admittance at the output port, thereby further increasing the output power at the output port.
