Abstract:
1. An apparatus comprising: a diode device to receive an incoming radio frequency (RF) signal to be amplified in a gain device of an amplifier and to provide a pre-distorted signal; the gain device to receive the pre-distorted signal and to output an amplified RF signal, wherein the diode device is to pre-distort the incoming signal with a substantially inverse distortion of a non-linearity of the gain device such that the amplified RF signal is a substantially linear version of the incoming RF signal; and a second diode device to receive the incoming RF signal and to provide a second pre-distorted signal to a second gain device, wherein the second diode device and the second gain device are connected to a supply voltage, and wherein the gain device and the second gain device form a complementary gain stage, and the diode device is coupled between a reference voltage and a gate terminal of the gain device and the second diode device is coupled between the supply voltage and a gate terminal of the second gain device.
