Reference no: EM131037752

8.79 A bipolar cascode amplifier has a current-source load with an output resistance βro. Let β = 50, /VA/ = 100 V, and I = 0.2 mA. Find the voltage gain Av .

D *8.80 Figure P8.80 shows four possible realizations of the folded cascode amplifier. Assume that the BJTs have β =100 and that both the BJTs and the MOSFETs have / VA/ = 5 V.

Let I =100 μA, and assume that the MOSFETs are operating at /VOV/ = 0.2 V. Assume the current sources are ideal.For ach circuit determine Rin , Ro, and Avo. Comment on your results.
