Exponential functional relationship generator method and system for implementation in digital logic

摘要

A system and method for developing a digital control signal Y for setting a target module (D) according to a digital setpoint signal A, a digital feedback signal C, a difference digital signal X=A-C in an exponential relationship, such that Y=2X+1-1. An N bit digital signal X is translated exponentially via a simple, non-complex programmable array logic unit to an expanded N+q digital bit signal providing an exponentially expanded response for the control signal Y to reset the target module D to an optimally desired setting.
