A 213-nW/Channel Analog Euclidian Vector Normalizer.

This brief presents a novel low-power analog Euclidian vector normalizer for analog signal processing in vector forms, such as the preprocessing of sensor array signals. Instead of using multiple stages of translinear circuits to synthesize the Euclidian norm with square root, squared sum, and division functions, this circuit performs concurrent Euclidian vector normalization on input signals with...
