a class-AB might amplifier is to be planned coercion a 6.0W, 12 load. Darlington might transistors with =1250 and rated at 19W coercion =150 C, are helpful. A diode detrimenting network with diodes of attachment greatness 1/20 that of the might transistors is to be used to impart class AB agency.
a) What is the optimum and <(max)>?
b) if we claim that the currect through the diodes diversify by no more than a rudiment of 6, what (floating beginning) is essential and what results?
c) Suppose that the solely might contribute helpful has Vs = ±15V. VL(Max) does referable veer, and neither does the Idetriment claimment. But VL(worst), PD(worst, classB) , and PDQ do. What are their values?
D) What is (worst,total)?
e) What greatness ardor sinks are needed coercion each transistor if we claim a insurance margin = 25 C
