【Abstract】 An auto-companding technique on analog circuit b e havioral modeling based on wavelet collocation method is proposed.The compandin g f unction is automatically constructed according to the input/output function of any given circuit block.Such a general-purpose technique can be applied to the au tomatic modeling of arbitrary building block of arbitrary I-O function.Moreover ,compared to the published modeling approaches,this method works more efficient ly in reducing both the modeling errors and the number of basis functions.更多还原
