Differential Amplifier

Amplifies the difference between two inputs while rejecting common-mode signals.

Formula (matched resistors)

V_out = (Rf / R1) x (V1 - V2)

Requires R1 = R2 and Rf = Rg for proper common-mode rejection.

हल किया गया उदाहरण

V1 = 3 V, V2 = 1 V, R1 = 10k, Rf = 50k.

  1. Gain = 50 / 10 = 5 V/V
  2. Differential input = 3 - 1 = 2 V
  3. V_out = 5 x 2 = 10 V
