Current and proposed Nuclear Physics (NP) experiments require very accurate
measurement of very short-lived phenomena at a very large number of very close
measurement locations. Available
data acquisition systems use currently available analog-to-digital converter
(ADC) technologies, which cannot be packed densely enough to extract all of the
available information from these experiments. Current
ADC data transfer speeds, power consumption, pin count, and mutual
electromagnetic interference levels have compromised the ability to measure and
understand many small-scale phenomena. This
project will develop a new architecture that combines a proprietary high-speed
(500 Ms/s), high-resolution, flash/folding ADC core with a proprietary high
speed (up to 30 GB/s), multi-level (ternary) serializer/deserializer (SERDES)
interface. Phase I developed the ADC
architecture, performed computer simulations of the basic ADC blocks, and proved
the feasibility of the proposed concept. The computer simulation indicated a
maximum data rate of 30 Gb/s at the high-speed digital ADC output. A
bench prototype of the ternary interconnect, based on off-the-shelf components
and operating at 12 Gb/s, was demonstrated.
In Phase II, the ADC and SERDES will be integrated into a set of
mixed-signal ICs, which will be manufactured using an advanced commercial high
density SiGe fabrication process. Phase
II, will design and fabricate ADC and SERDES Application Specific Integrated
Circuits (ASICs) and integrate the developed product into a functional data
acquisition system.
Commercial
Applications and Other Benefits as
described by awardee: The
technology should reduce complexity and improve the performance of next
generation data acquisition systems used in a variety of experiments at multiple
DOE research facilities. Other
applications include homeland security, wireless ground station, medical image
processing, telecommunications, and process control.
