Translinear circuit for generating arbitrary power-law functions

A new technique for designing arbitrary power-law circuits is presented. The technique, using only bipolar junction transistors and current sources, is simple and flexible and can be used to design power-law circuits with integer and non-integer powers and powers in the form of the ratio of two integers. The proposed technique results in programmable and integratable circuits. Simulation results illustrating the applications of the proposed technique are presented. (C) 1998 Elsevier Science Ltd.
