Abstract

A 4 b flash-type A/D converter (ADC) with pipelined encoder has been implemented in a SiGe bipolar technology for very high-frequency mixed-signal applications. The chip is fully functional at 8 GSample/s. Maximum input bandwidth is 4 GHz based on beat frequency measurements. Both DNL and INL are within 0.25 LSB. The chip includes over 1000 transistors and consumes 500mW at 3.6V.
