1 Introduction There have been many excellent collections of op-amp circuits in the past, but all of them focus exclusively on split-supply circuits. Many times, the designer who has to operate a circuit from a single supply does not know how to do the conversion. Single-supply operation requires a little more care than split-supply circuits.
