can someone help me with the transfer function of the circuit attached below.. it is a differentiator followed by an integrator

 

I don't see a differentiator. The first opamp is a differential amplifier that is not needed since the input is single-ended.

The second opamp and transistors is a simple first-order integrator (lowpass filter) with a gradual 6db/octave slope. The transistors are not biased so they will produce horrible crossover distortion.

 

Thank you very much Audioguru..
Yes the first is a differential op amp, would you know how to derived Vout/Vin for the circuit??

There are so many crossed and joined wires that I can't see what is joined.
It looks like both inputs of the differential amplifier have the same signal so the output will be almost nothing.
