I have the problem in assuming the Vout of the circuit and secondly...do i also need to consider the Vcc in the diagram?
Thanks in advance...
 

Hi,
If you need to calculate the transfer function, I suppose you are in the small-signal domain. Hence, you do not need to consider Vcc. Then:
  1. Get the small-signal model of the MOSFET (common-source if it is a pMOS, common-drain if an nMOS)
  2. Consider the opamp one-pole transfer function: Vout(s) = Vd(s) * A(s), in which A(s) = A0 / (1 + s / w0)
  3. Redraw the entire diagram by using blocks instead of opamp and MOSFET
Regards,
Rik
 

how can we find transfer function of sinc function?
 

The Fourier's transform of the sinc function, is the rect function.
