Abstract :
This paper presents a high-speed 4 bit full-flash analog-to-digital converter with a new parallel reference network for an UWB radar. The ADC is implemented in 190 GHz SiGe BiCMOS technology, has more than 6 GHz effective resolution input bandwidth and operates up to 16 GSample/s. Power dissipation is 1.15 W including test buffers and 750 mW of the converter itself.
