Abstract

A 5-bit 10 Gs/s DAC for Spectral Encoded UWB transmitters is presented. A test counter is integrated on-chip to facilitate performance measurement. The chip has dimensions of 1.0 x 1.5 mm, and is implemented in a 0.18 mum SiGe BiCMOS process. The DAC operates at conversion rates of over 10 Gs/s with a power dissipation of 12 mW. Linearity results of the DAC at 5 GS/s are presented, with the DNL < plusmn0.5 LSB and INL < plusmn0.8 LSB.
