Abstract :
Pipelined ADCs designed in analog BiCMOS technologies can offer good linearity and high SNR performance for input signals with reasonable voltage swings. Such ADCs, however, face two critical design challenges: the process limits the sampling rate, and the pipeline architecture limits power efficiency. This paper introduces a two-way time-interleaved (TI) switched-current 1Gs/s 12b pipelined ADC in SiGe BiCMOS that addresses these issues.
