Abstract
Methods and systems using Pade' Approximant expansion ratios provide mappings between nonlinear sensors and a more linear output domain. The method includes a method of converting an input digital signal having a nonlinear dependency on a physical variable into an output digital signal that exhibits a substantially linear dependency with respect to the variable is disclosed. The method includes: (a) multiplying the input digital signal by a variable multiplying factor to thereby generate a multiplied digital version of the input signal; (b) adding to the multiplied digital version of the input signal, a predefined digital offset signal to thereby produce the output digital signal; (c) multiplying the output digital signal by a predefined feedback gain correction factor to thereby produce a digital feedback signal; (d) using the digital feedback signal to produce the variable multiplying factor.
