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