Vector quantization systems are usually based on digital implementation of the core operations.
In this paper, video compression systems exploiting an analog implementation of vector
quantization are 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 described.
