Abstract

We present the first 90-nm digital CMOS RF power amplifier. This PA contains a large array of NMOS switches, and performs a direct digital-to-RF-amplitude conversion, filtering and buffering in a fully-integrated GSM/EDGE transmitter. Power control is fully digital. 40% efficiency is obtained at 10-dBm output power from 1.4 V and it occupies 0.005 mm/sup 2/.
