Low-power reconfigurable baseband block for UMTS/WLAN transmitters

A low-power reconfigurable analog baseband block for UMTS/WLAN transmitters is presented. The law-power pe6ormance is guaranteed by the innovative architecture that allows to directly connect the output DAC current with the reconstruction analog filter. The DAC and the baseband filter, have been designed in a 0.13pm CMOS technology with a power supply limited to I.2K The current consumption, has been optimized for the selected UMTS or WLAN standard and it equal to 7.9mA and 10mA, respectively.
