In this article, we'll discuss two benefits of using an active load: improved biasing conditions and differential-to-single-ended conversion.

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. Single amplifiers are usually implemented by either adding the appropriate feedback resistors to a standard op-amp , or with a dedicated integrated circuit containing internal feedback resistors. It is also a common sub-component of larger integrated circuits handling analog signals. In practice, however, the gain is not quite equal for the two inputs.

In part this is because they are conveniently implemented in silicon technology. It is also a result of the use of monolithic integration and the maturity of semiconductor technologies resulting in repeatable RF active components. Differential amplifiers are the preferred amplifier topology with RFICs. Since substrate noise is common to all nodes of a differential amplifier, there is little differential substrate noise signal. Also, differential circuits lend themselves to current-mode biasing which is preferred onchip.

In this op amp, simple inversely connected current-mirror pairs are used as active loads.
