3) CS amplifier shown below is biased by a constant-current source I. Let Rsig 0.5 M, RG -2 MQ, gm -3mA/V, Rp -20 k2, and RL 10 k2. Find the midband voltage gain and the lower 3-dB frequency with...
2. A CS amplifier is driven by a signal source with Rsie = 100 k2, and has load resistance RL = 100 k.2. Assume CL = Cgs = 0.1 pF, Cgd = 50 fF, gm = 1 mA/V, and r. = 100 k22. (a) Find the midband voltage gain. (b) Use open-circuit time constants to find upper 3-dB frequency fu.
Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
A common source amplifier circuit based on a single n-channel MOSFET is shown in Figure 4b. Assume that the transconductance gm-60 mS (equivalent to mA/ V) and drain source resistance, os, is so large it may be neglected. 0) Calculate the open circuit voltage gain Av Yout/ Vis. i) The amplifier has a load of 10 k2.
