Abstract :
A fully integrated transmitter front end with on-chip power amplifier (PA) in 0.18 um CMOS technology is presented. The on-chip PA employs dynamic bias technique to reduce power consumption and enhance linearity. In the measurement, it reveals the output PldB of the PA is 26.5 dBm. Also, the transmitter delivers an average power of 17.3 dBm with EVM of -28.1 while drawing 225 mA of DC current (PA 157 mA) from 3.3 V supply. The low power consumption, adequate linearity and high integration make this transmitter suitable for WLAN application.
