Abstract

This paper presents a reconfigurable baseband DAC system (current-steering D/A + transimpedance stage + low-pass reconstruction filter) operating in a low-voltage multistandard transmitter, while satisfying high linearity requirements. The implemented block can process the WLAN 802.11 a/b/g and the UMTS signals. The device has been integrated in a 0.13 μm CMOS technology and operates with a 1.2 V supply voltage. Experimental results show that the proposed circuit achieves a 29.5dBm OIP3 when configured for the WLAN setting, and a 31 dBm OIP3 when configured for the UMTS setting. The current consumption, optimized for the two cases, is 16.2 mA/14 mA for WLAN/UMTS, respectively.
