Abstract: An exemplary structure has an output stage; a driver stage; and a power stage connected between the driver stage and the output stage. The power stage includes a first transistor and a second transistor connected in series between the driver stage and the output stage. The power stage also includes a third transistor and a fourth transistor connected in series between the driver stage and the output stage. An inductor has a first terminal electrically connected to a first node between the first transistor and the second transistor and a second terminal electrically connected to a second node between the third transistor and the fourth transistor. The inductor is configured to provide impedance matching between common-gate stages of the power stage.
