HARMONIC DISTORTION MACRO MODEL CORRECTION USING A MEMORY TABLE

摘要

A method of harmonic distortion (HD) macro-model error correction uses a HD simulation macro-model for an electronic device and memory table storing an operating condition/variable that affects HD and HD coefficient value(s). A processor runs the macro-model using information in the memory table for generating HD simulation values. The memory table is initially filled with a first condition/variable and initial HD coefficient. The processor runs the simulation macro-model for generating an initial HD simulation value. An initial Datasheet to initial HD simulation error (D-S error) is determined. Provided the magnitude of D-S error is above a predetermined error bound (PEB), an updated HD coefficient is used for repeating the filling, generating an updated HD simulation value and determining D-S error to obtain a corrected HD coefficient(s) which reduces the D-S error
