Question

Write a Matlab code that is able to plot the frequency response for the given circuit.

​​​​​​​

Tvoo Ro Vinot - Vout . Vout 9m Vin Ro = CL Vin EMEL hu (b)

Answer 1

first we have to converted in to small signal model of given ciruit which as given to find the transfer function for the frequency respone and then use matlab for plotting the response as attachment
