This book illustrates the design challenges when analog circuits are used in massive parallel systems. The usage of a bio-inspired scheme for sound processing is new and little or no circuitry has been developed to date to support such processing. This book illustrates how appropriate circuits can be built, highlighting the importance of accuracy and system analysis using analog circuits. Many of the illustrated circuits were fabricated. The measured results from the integrated circuits are compared with the theoretical predictions as well with the results from circuit and Monte Carlo...
