Differential Amplifiers Quiz

A differential amplifier amplifies the difference between two input voltages while suppressing any voltage common to the two inputs.

The ideal output equation for a differential amplifier is $V_{ ext{out}} = A(V_{ ext{in}}^{+}-V_{ ext{in}}^{-})$, where $A$ is the gain of the amplifier.

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.
