The Integrator itself is built using a transconductor (VCCS) and capacitor. OPAMP= VCCS + Capacitor. The differential amplifier in OPAMP takes the input difference
@@NaaJeevitham500 That is correct but my doubt is different. The action of OPAMP is to take diffence of two signals and amplify it to give the output i.e. Vout = A(V1 -V2)... This is the action of OPAMP....But sir told in the video that in negative feedback the difference and integration both can be done through OPAMP...But OPAMP would not do integration directly... If you consider an OPAMP as black box then it will take the difference of two signals and give an amplified version of that difference signal which is the output of OPAMP... Obviously as per negative feedback amplifier concept, we have to take integration of error signal and that is why Sir has introduced VCCS and the output current has flown through Capacitor to emulate the behavior of integrator and total block (VCCS +Capacitor) he called as OPAMP... Is it correct to say it as OPAMP?
By opamp, he doesn't mean the final opamp comes in the form of packaged chips which amplifies the difference in the voltages of its terminals. We are attempting to realise it, but we are not there yet. By opamp he means the opamp which we design using differential pairs, to which there will be a capacitor connected at its output terminal. That capacitor will integrate the output signal. Thats what he means by opamp which takes the difference and intergrates it.
great Lecture Series
Sir! How the OPAMP is helping in calculation of Integration?

Day 1 LEC 4
thanku sir Ji
Nice
Quarantine day 4
29:00
At 10 minutes Vo /Vi should be wu/w instead of w/wu .. This mistake propagates throughout..
To be exact, that unintentional mistake happened at 13:55.
