Why is it impossible to create an ideal operational amplifier?
Characteristics between ideal and practical operational amplifiers are explained with comparision..!
With that I am going to tell that the real op amp is most impossible to create and vulnerable..!
Hope you understand the explanation..!
Have a good day..!

10. The operational amplifier in the circuit shown below is ideal. The voltage of the ideal sinusoidal source is y(t) = 30cos(106t) V 10 nF How small can Co be before the steady- state output voltage no longer has a pure sinusoidal waveform? a) 100 Ω b) For the value of Co found in (a), write the steady-state expression for vo(t) ↓ 25Ω Co 2,0 100Ω
What is more critical for reducing the gain distribution of an operational amplifier and why is that so? Operational amplifier selection or resistor selection?
Using ideal op-amps, design operational amplifier circuits that will yield the following outputs: (a) Vo = 20 Vin (b) Vo = -Vin (c) Vo = Vin (d) Vo = -10Vi1 - 16Vi2
For this problem, you may assume that the operational amplifier is ideal. For the circuit below, find the output voltage Vout, given R1 = 1k ohms, R2 = 4k ohms and Vs = 1V. OUT Select one: O a.- 0 6.5 c. 1.25 d. -4 O e. -0.75
