Abstract
Wireless circuitry is provided that includes an antenna and a radio-frequency amplifier coupled to the antenna. The radio-frequency amplifier can include a first input transistor having a drain terminal coupled to a first node, a second input transistor having a drain terminal coupled to a second node, and a common mode impedance tuning circuit coupled between the first and second nodes. The common mode impedance tuning circuit can be configured to tune a common mode impedance at the first and second nodes of the radio-frequency amplifier. The common mode impedance tuning circuit can be configured to provide a first common mode impedance when the amplifier is operating in accordance with a first set of operating conditions and can be configured to provide a second common mode impedance, different than the first common mode impedance, when the amplifier is operating in accordance with a second set of operating conditions.
