Systems, methods, and apparatuses for improving reliability and/or reducing the likelihood of breakdown of an amplifier or a component thereof. A system can include a sensing circuit electrically coupled to a transistor of the amplifier and configured to sense an AC voltage associated with the transistor. A protection circuit can be electrically coupled to the sensing circuit and the amplifier and can be configured to supply a DC voltage to the transistor of the amplifier based on the AC voltage sensed by the sensing circuit.
