Abstract
An analog implementation of vector quantization is presented. The main advantages of
analog design are exploited, obtaining notable performances when compared to other
solutions found in the literature. The circuit features a very modular, completely
parallel internal architecture. Many circuits can be easily connected to obtain a
larger codebook size and a larger vector dimension. Synthesis of codebooks is also
possible thanks to the long-term, digital storage realized off-chip.
