A Physical Interpretation of the Distance Term in Pelgrom’s Mismatch Model results in very Efficient CAD
(IEEE Computer Society, 2007)
In 1989 Pelgrom et al. published a mismatch model for MOS transistors, where the standard quadratic deviation of the mismatch in a parameter between two identical transistors, is given by two independent terms: (1) a ...
