Consider the differential amplifier shown and assume identical transistors. If = (1)( 0.5)2 , 3 = 4 ,
= 0.5, = 1, = 10 and = 100. Also, let 1 = 2 and 3 = 50
1) Find the value of 2 to get the correct current through 3.
2) Find the range of values for to have M1 and M2 in saturation.
3) Draw differential-mode half circuit.
a. find the single ended gain.
b. find the differential mode gain.
4) Draw the common-mode half circuit.
a. find the single ended gain.
b. find the common mode gain.
5) If there is mismatch in by 10%. What is the common mode gain?
