Question -4; Vo . The figure represents the VTC of a MOSFET in a common source configuration, where the saturation region extends from Vto v. Only a small portion of the region (VSVI < 236V) is used for amplification. Assume the signal to be amplified is given as: Vilt) = 0'l sin Crot) Under small signal approximation, if the input signal is given as Vz(t) = Voc+ Vict) the output of the amplifier will be Vo(t) = Voccout) + Avi(t) 2'36V VOD 2 VI Let, The MOSFET with common source circuit has the following parameters . V = Tv K = 1 mA/u2 R=5ka and VDD=7V (a) Find the bias point of the input (Voc), assuming that the point will, be at the centre of the amplification region. Find the bias point of output signal (Upc cours). [Hint: when VI = VDC Vo = Voccout) ] CD (c) Find the gain of the MOSFET Amplifier. (1) Find out the amplitude of the input and outputo voltage Wareforms . [ Hint: Vo = AV:]
