Abstract: An amplifier may include a first transistor. The amplifier may also include a second transistor coupled to the first transistor in an output stage of the amplifier. The amplifier may also include a level shift resistor coupled between a gate of the first transistor and a gate of the second transistor. The amplifier may further include a feedback bias circuit coupled to the gate of the first transistor and the gate of the second transistor through the level shift resistor. The feedback bias circuit may be configured to sense a common mode voltage of the output stage of the amplifier, and to compare the common mode voltage with a reference voltage to control a resistor bias current conducted by the level shift resistor.

Abstract: A method for inductively coupled communication is described. The method includes generating a first signal. The first signal frequency is a first integer multiple of a carrier frequency for inductively coupled communication. The method also includes selecting between a standalone mode and a coexistence mode. The method further includes dividing the first signal to obtain a second signal when in standalone mode. The second signal frequency is a second integer multiple of the carrier frequency. The method additionally includes dividing the first signal to obtain a third signal when in coexistence mode. The third signal frequency is a third integer multiple of the carrier frequency. The method also includes generating an inductively coupled communication signal using at least one of the second signal and the third signal.
