Abstract
A signal amplifier having an inverted topology may include: a first common source-type amplifying unit connected to a power supply terminal and amplifying a first band signal among input signals; a second common source-type amplifying unit connected to a ground terminal and amplifying a second band signal among input signals; and an output matching unit performing impedance matching with respect to a first band between the first common source-type amplifying unit and an output terminal and performing impedance matching with respect to a second band between the second common source-type amplifying unit and the output terminal. The first common source-type amplifying unit, the output matching unit, and the second common source-type amplifying unit may form a single current path between the power supply terminal and the ground terminal.
