Thanks for the help audioguru! :)

Where I have more difficult anaslysing the circuit its in the opamp part... I dont know how to calc the transfer function of it  ???

Sorry...I hope it

Im studying realimentation in electronic circuits, I know that for have transconductance gain the circuit have to be of serie-serie type....I have V in the entry and I in the out of it.

To have a transfer function of it I divided in two parts: A=>the amp-op and the part of diodes and transistors and 2) Beta=>the two Resistances of 1kohm.
This way I think I can calculate the transfer function of the circuit to a form A/(1+Beta*A)

In the diodes and transistor part the gain it

Hi,

I have to analyse this circuit and know what it does...

I think its an transconductance amplifier...but I need to know how to find the transconductance gain of it....

the circuit its int the following link
