Contour modulation is a technique in which a phase-modulated signal waveform and amplifieroutputimpedance work together to maintain higher efficiency over a sizable output power back-off.
No matter what the outputimpedance of the amplifier is!

After discussing how the input offset current influences the output of operational amplifier, the optimal relationship between peripheral impedance is obtained.
