ABSTRACT:
The universal CMOS current-mode analog function synthesizer is based on approximating the required function using its sixth-order Taylor series expansion. These approximations can be implemented by adding the weighted output currents of a number of basic building blocks built around a basic current squarer, and a constant current. The circuit can simultaneously realize thirty-two different mathematical functions and can be easily expanded to accommodate many others.
