Abstract:
1. A method comprising: generating a plurality of control voltages using an input transformer with a single primary side and two secondary sides, wherein the single primary side receives a control current and the two secondary sides provide the plurality of control voltages; amplifying the control voltages using a power amplifier stage that comprises a first transistor and a second transistor arranged in parallel, wherein the first transistor is a metal-oxide-semiconductor field-effect transistor (MOSFET) of a first type and the second transistor is a MOSFET of a second type that is different from the first type, wherein the first transistor and the second transistor are arranged in a push-pull configuration; and outputting an output voltage as a function of the amplified control voltages using an output transformer that comprises two primary sides and a single secondary side, wherein the two primary sides receive the amplified control voltages and the single secondary side provides the output voltage as a function of the amplified control voltages.
