Designing non‐linear single OP‐AMP circuits: A cook‐book approach

摘要

AbstractThe inherent saturationnon‐linearityof the op amp is used to design circuits having a wide variety of useful non‐linearv‐icharacteristics. These circuits are made of one op amp and 3 or 4 linear resistors which are passive under a rather mild assumption derived from the 3‐port paramountcy condition. Explicit design formulae are given for each prototype circuit and numerous examples are given and validated by actual measu
