Op-Amp Integrator: Practical Integrator with Frequency Response(Hindi)

Practical Op-Amp Integrator Contents The timestamps for the different topics covered in the video is given below: 2:18 Need of Rcomp and Rf 6:38 Expression of output voltage 11:58 Frequency Response of Practical integrator 22:19 Condition for proper integration 24:11 Applications of Integrator Practical Integrator: It performs mathematical operation of integration w.r.t time. The limitations of ideal integrator can be minimized in practical integrator that uses Rf parallel with capacitor Cf and Rcomp used to minimize errors due to input bias current Need of Rcomp and feed back resistance Rf The feedback resistor Rf reduces and restricts the low frequency gain to a finite value equal to Rf/R1. Rcomp used to minimize errors due to input bias current Frequency Response of Practical Integrator 1. At f=0 IAI=Rf/R1 2.At f=fa(break frequency/corner frequency) IAI reduces by 3dB 3. At f-fb(Unity gain frequency) IAI reduces to 0dB Applications : In Analog computers to solve differential equations In A to D converters In Signal wave shaping circuits(Ramp wave and triangular wave generators) In integral type controllers used in C.L control systems.
