Abstract : This report summarizes accomplishments made under Grant No.: NOOOl4-93-l-lOO7 for providing ADC Test Support to the ARPA HBT/ADC technology development program during the period of 1 Nov through 31 Oct 94. The following were accomplishments for this period. 1) Recruited and trained one graduate assistant to study ADC architectures and error modeling procedures. 2) Participated in the ARPA HBT/ADC design review on 26 Apr 94 and presented initial results relating ADC error basis functions to specific error phenomena. These results represent new procedures and ways to characterize ADCs based upon architectural error models. 3) Recruited an advanced graduate student in Jun 94 to begin implementation of orthogonal search procedures to facilitate ADC error modeling with the use of many-element basis sets. This student has recently started to develop simulation procedures for Delta-Sigma ADC architectures and their error effects. 4) Visited Lincoln Laboratory on 28 Jul 94 to review status of probe testing hardware development and prototype testing and evaluation plans. 5) Obtained and evaluated raw data samples obtained from Lincoln Laboratory for a 4-bit TRW prototype sampled at 1 GHz. 6) Wrote and submitted two papers for the 1995 IEEE International Symposium on Circuits and Systems dealing with ADC error modeling procedures developed under this program.
