hi , i?need?solution for question 3 only and need urgently


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, ?1=?2=0.01 V-1, I1=5 mA

 


 

Figure 1.

 


 

Question 2

 

The circuit shown in Figure 2 has the following parameters:

 

IREF= 50 ?A, -VEE=-5 V, ?=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?
