    Hello i am new to this forum.

    I want to design a circuit with 5 opamps that implements this function transfer: G(s)=10/[(s+1) (s+5)]

    it must be like this: https://www.dropbox.com/s/opsaabvrvighvqm/opamp.JPG?dl=0

    i don't know much about this type of project but any help would be great.

    Thank you

    You may not know much, but we know absolutely nothing. Not nearly enough information. WHY? What is the project, what is the input signal, what is the desired output signal, why use that specific transfer function, why use that specific circuit, and on and on and on...

    Sounds like homework since a nice clean formula is given. This is a second order low pass filter with a gain of 10 and a very low cutoff frequency. Why 5 opamps? It can be done with one. But if you have to use opamp integrators, I suppose two of those for the filtering, one more for the gain, plus one each for input and output buffers? Seems like overkill to me.
