Practical Op-Amp Integrator
Contents
The timestamps for the different topics covered in the video is given below:
2:20 Need of Rcomp and Rf
5:21 Expression of output voltage
10:22 Frequency Response of Practical integrator
18:11 Condition for proper integration
19:56 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
