In digital radio systems, high data transmission rates require the use of spectrally efficient linear modulation techniques; however, these techniques are generally sensitive to nonlinearity caused by the high-power amplifier (HPA) employed in transmitter systems. The nonlinearity of HPA is potentia
## Abstract A 900βMHz linear power amplifier with an adaptive bias scheme is fabricated using a 0.25βΞΌm CMOS technology. The power amplifier operates over the range of 860β960 MHz, which is the ultrahighβfrequency band for radio frequency identification (RFID). All matching networks and RF chokes a
