摘要：
A power amplifier, supplied by a supply voltage, to drive an antenna to output a magnetic field, comprising a differential stage configured to output an output signal to drive the antenna, and a feedback stage configured to receive a common mode output voltage from the differential stage and to output a feedback voltage to regulate the output common mode signal to be proportional to the supply.
