摘要：
A 5-bit 10Gs/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 1.5mm, and is implemented in a 0.18 mu m SiGe BiCMOS process. The DAC operates at conversion rates of over 10Gs/s with a power dissipation of 12mW. Linearity results of the DAC at 5GS/s are presented, with the DNL < +/- 10.5LSB and INL < 0.8LSB.
