RC Integrator

Calculations & Observations



Fig.1 RC Integrator circuit
Let V_i = alternating input voltage and i = resulting current. Applying Kirchhoff’s Voltage Law to RC low pass circuit,

Multiplying throughout by C, we get

as RC >> T, the term, " ∫_o^t i dt " may be neglected

C V_i = iRC
Integrating with respect to T on both sides, we get
