A 12-bit 320-MSample/s current-steering D/A converter in 0.18-/spl mu/m CMOS is presented. In order to achieve high linearity and spurious free dynamic range (SFDR), a large degree of segmentation has been used, with the seven most significant bits (MSBs) being implemented as equally weighted current sources. A "design-for-layout" approach has allowed this to be done in an area of just 0.44 mm/sup 2/. The increased switching noise associated with a high degree of segmentation has been reduced… CONTINUE READING
