Abstract: A system for a power transmitter may be provided. The system may include a first amplifier stage having at least a first transistor and a second transistor that are connected in a first cascode configuration; a second amplifier stage having at least a third transistor and a fourth transistor that are connected in a second cascode configuration, where the first transistor receives a system input of the power transmitter, where the second transistor is connected to the third transistor, and where the fourth transistor provides a system output of the power transmitter; and a feedback network that connects a first gate or base of the fourth transistor with a second gate or base of the second transistor.
