Regulation of an amplification apparatus

摘要

An amplification apparatus includes an amplifier. The amplification apparatus includes a bias voltage circuitry coupled to the amplifier to provide a bias voltage thereto. The amplification apparatus includes a supply voltage circuitry coupled to the amplifier to provide a supply voltage thereto. The supply voltage circuitry is coupled to the bias voltage circuitry. The bias voltage circuitry is configured to provide the bias voltage depending on the supply voltage.
