Abstract—An energy-efficient, 3.5-GHz, direct-conversion RF
transmitter with integrated 23-dBm, Class-B power amplifier
(PA) is fabricated in a 0.13-
m CMOS process for the reliable
transmission of 20-MHz bandwidth OFDM signals. Assisted by an
integrated feedback path, a two-dimensional, digital look-up table
(2-D LUT) adapted by complex gradient-descent algorithms com-
