# Integrator Circuit With Reset

Integration is one of basic signal processing that can be done in analog domain. Using operational amplifier (op-amp), integration operation can be done with very simple circuit with very high accuracy. Here is the schematic diagram of an integrator circuit:

The resistor R2 should have the same value with R1 since R2 is employed to minimize the offset error due to bias current. [Source: National Semiconductor Application Notes]
