Single-Supply Circuit Collection Amplifiers
What configurations are available for single-supply op amp design?
Many types of amplifiers can be created using op amps. Single output op amps can be configured to either invert or not invert the signal. In addition they can be used for level shifting, gain and filtering.
The following links allow selection of some basic, single-supply op amp circuits that are useful to the designer during the concept stage of a design. The circuit configuration and correct single-supply dc biasing techniques are presented for the following cases: inverting, noninverting, differential, T-network, buffer and ac-coupled amplifiers.
Input offset compensation must be handled differently dependant on whether the amplifier is inverting or noninverting. In addition, the offset may be done in either input and either polarity.
