The MOSFET has V 1V and ke 16 mA/V² (a) Find the value of gm at which the device is [3 points] operating (b) Find the midband gain Vo/Vaig in V/V and in [4 points] dB. (e) Find the value of Cs that places the lower 3-dB (4 points] frequency eg, at 100 rad/s. (d) If Cg = 1 pF and Cgd=0.2 pF, find the value [4 points] of the upper 3-dB frequency, co (e) It is desired to double oy by changing the [10 points] value of g (through changing the bias current I), find the required value of I, the new value of the midband gain (in V/V and in dB), and the new value of w -15 V Figure 10.10.1
