A Single Supply Op Amp Circuit Collection (PDF 27p)

EBook Description: 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. The designer should read and understand this introductory material.

The solution was to first build an amplifier that had more gain than the application required. Then some of the amplifier output signal was fed back to the input in a manner
that makes the circuit gain (circuit is the amplifier and feedback components) dependent
on the feedback circuit rather than the amplifier gain.
