Gain of a differential amplifier

WebAug 13, 2024 · Practical differential amplifier. A practical differential amplifier using uA741 opamp is shown below. With used components the amplifier has a gain of around 5. Remember the equation Av = -Rf/R1. Here Rf = 10K and R1 =2.2K, -Rf/R1 = -10/2.2 = -4.54 = ~-5. Negative sign represents phase inversion. WebOct 12, 2024 · Since a fully differential scheme will be adopted in this design, the circuit could also provide a negative gain for the negative output V out − to form a positive feedback when the whole differential circuits are realized.

WebIn the above equation, A is the differential gain and Vin+ and Vin- are the i/p voltages. In practice, the gain is not equal for the inputs. For example, if the two i/p voltages are equal, then the o/p will not be zero, A more accurate expression for a differential amplifier comprises a second term. WebAF is used to represent the open-loop differential gain of the amplifier such that (V OUT+) – (V –) = AF(VP – VN). This assumes that the gains of the two sides of the differ-ential amplifier are well matched and that variations are insignificant. With negative feedback, this is typically the case when AF >> 1.
