Design of a diode function generator using the diode equation and iteration

A resistor-diode network topology is described which permits a simple iterative solution for the network resistors in order to satisfy a given nonlinear input-output specification. The diodes are modeled by the diode equation giving excellent accuracy over a wide range of diode operation. Combining operational amplifiers with the basic resistor-diode topology permits the realization of a general single-valued continuous nonlinear function.
