An analogue vector matching architecture

  • S. Collins

A two transistor analogue circuit is described which exploits the native device characteristics of a MOSFET to calculate the square of the Euclidean distance between two points. Simulations suggest that this circuit can be employed as the basis of a low-power vector matching architecture which could be used for vector quantisation or nearest neighbour classification.
