In one embodiment, an apparatus includes an amplifier circuit having a phase shift. The amplifier circuit amplifies a signal for wireless transmission. A feedback circuit is coupled to the amplifier circuit and includes a capacitor. An input impedance to the amplifier circuit has a same impedance characteristic as a feedback circuit impedance of the feedback circuit. A total phase shift of the signal for the amplifier circuit and the feedback circuit is less than a threshold.
