Abstract (en)

[origin: WO2014130075A1] An amplifier circuit (1000) amplifies a signal for wireless transmission. A feedback circuit (208), including a capacitor, is coupled to the amplifier circuit. Components of the feedback circuit (208) are selected based on a feedback factor such that an input impedance (Z input) to the amplifier circuit (1000) has a same impedance characteristic as a feedback circuit impedance of the feedback circuit (208).
