I need quick help this question please less than 30 minutes the answer

tonains b pages, 3 questions and the duration is 120 minutes. 2s A4 cheat-sheets and calculators are allowed QUESTIONS he following current controlled signal attenuator circuit.เ is a DC current source that controls the attenuation factor. R.-4kf2 and k-4 mAN v™-osv ter the diode connected MSRT device.V" is a sinusoidal input signal. Coupling capacitors C-c, are very large they bibck lhe DC current and pass the AC signals. Answer the following questions a. (10 pts) Use the MOSFET small signal model to find an expression for V/Vn. (Hint: Find the equivalent resistance of the diode connected MOSFET device.r,can be neglected) b. (10 pts) if V-10mV sinusoidal, calculate Vau for 1-640A. c. (10 pts) Calculate the value of f which sets u V/2 Vin 81
