Abstract
A DAC+filter is realized in a 0.13μm CMOS technology to operate in a multistandard (WLAN/UMTS) transmitter. The 0.8mm device allows programming the 8 bit DAC sampling frequency (100MHz/50MHz) and the 4th-order low-pass filter bandwidth (11 MHz/2.11MHz) to satisfy the 8 bit WLAN/9bit UMTS standards, consuming 11mW/8.4mW from a single 1.2V supply. For both standards the OIP3 is larger than 29dBm and the SFDR is 54dB for WLAN, 61dB for UMTS.
