The system receives a 64/spl times/64 pels block of a gray scale image, extracting a feature vector from the image and recognizing the image by template matching. An analog associative processor is adopted as the template matching core because it features compact implementation as well as fast processing due to its fully parallel architecture. For generating feature vectors, dedicated digital CMOS circuits have been developed because of their versatility in the algorithm. The analysis of medical X-ray pictures (Cephalometric landmark identification by expert dentists) was taken as an exercise for the system, and intensive computer simulations have been conducted to optimize the recognition performance of the system. Although the entire system has not yet been implemented on a single chip, all the key sub circuits in the system were fabricated as test circuits and their correct functioning has been experimentally demonstrated. It is also shown by experiment that very low power operation of the template matching core is possible by operating the analog circuitry in the subthreshold regime without degrading recognition performance.","PeriodicalId":203750,"journal":{"name":"2002 IEEE International Symposium on Circuits and Systems.

Recently, a new class of /spl Sigma/-/spl Delta/ A/D converters was developed based on magnitude-squared or magnitude complementary signal and noise transfer functions to decrease the sensitivity to capacitor mismatches at the expense of slightly lower SQNRs and DRs. This paper is concerned with the development of a novel approach to the design of /spl Sigma/-/spl Delta/ A/D converters. This approach combines the transfer function complementarity (in the overall frequency band) with signal and noise transfer function magnitude complementarity (in the signal passband) to obtain a single /spl Sigma/-/spl Delta/ A/D converter with a cascade-of-resonators configuration. Consequently, the resulting A/D converters achieve not only high-stability (arising from magnitude complementarity), but also high DR and SQNR (arising from transfer function complementarity) in the SC hardware implementation. A practical application example is given to illustrate the results.","PeriodicalId":203750,"journal":{"name":"2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat.
