Question 2
The circuit shown in Figure 2 has the following parameters:
IREF= 50 µA, -VEE=-5 V, ß=125 and VA=40 V.
Determine:
a) The output current of the circuits based on n=1
b) Repeat part (a) for n=3.
c) What is the current source voltage (VCS) for n=3?
d) What is the minimum value of VEE?
Question 3
Use the Open-circuit time-constant technique and derive an expression for the fH of the circuit shown in Figure 3.
