A Low-Power CMOS Analog Vector Quantizer
نویسندگان
چکیده
We present a parallel analog vector quantizer (VQ) in 2.0m double-poly CMOS technology and analyze its energetic efficiency. The prototype chip contains an array of 16 16 charge-based distance estimation cells, implementing a 16 analog input, 4-b coded output VQ with a mean absolute difference (MAD) distance metric. The distance cell including dynamic template storage measures 60 78 m. The output code is produced by a 16-cell winner-take-all (WTA) output circuit of linear complexity which selects the winning template with constant power-delay product, independent of input levels and scale. Experimental results demonstrate 34 dB analog input dynamic range and 0.7 mW power dissipation at 3 s cycle.
