Question 1:
Determine the differential voltage gain (vo/(vi1-vi2)) of the circuit shown in Figure 1.
Assume:
K'n (W/L)= K'p (W/L)= 4 mA/V2, |Vt| = 1.5 V
VDD = 10 V, V1 = 7.8V, V2 = 7.5 V, λ1 = λ2 = 0.01 V-1, l1=5 mA
Question 2:
The circuit shown in Figure 2 has the following parameters:
IREF= 50 μA, -VEE= -5 V, β =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.
