MIXED-SIGNAL SYSTEM FOR PERFORMING TAYLOR SERIES FUNCTION APPROXIMATIONS

摘要

A mixed-signal system for performing Taylor series function approximations is disclosed. The mixed-signal system includes a digital-to-analog converter (DAC), multiple resistor-to-resistor (R2R) ladders, various digital registers, a digital processor and an analog integrator. The digital processor calculates coefficients F, F_x, F_y, F_xx, F_xy, F_yy of a Taylor series equation and calculates distance functions. The digital processor also includes a digital register for storing a magnitude scaling factor F (x ₀,
