Abstract :
A simple low voltage circuit topology able to generate any positive real number power-law function is presented. The proposed circuit exploits BJTs and is based on piecewise linear approximation of the nonlinear function to be generated. An in-depth mathematical analysis is deployed. The instances of a squarer, a cube-law, a square rooting and cube rooting circuit are thoroughly examined through simulation. The obtained results verify the theoretical calculations
