A BiCMOS fully-differential 10-bit 40 MHz pipelined ADC

Abstract

A BiCMOS fully-differential, 10-bit, 40 MHz pipelined ADC has been developed. The ADC can digitize not only a fully-differential but also a single-ended signal over a wide input range with little variation in performance. At f/sub s/=40 MHz, the ADC exhibits a signal-to-(noise+distortion) ratio (SNDR) of 57.1 dB and consumes <400 mW from a single 5-V supply.
