a dispose-AB might amplifier is to be planned ce a 6.0W, 12 load. Darlington might transistors with =1250 and rated at 19W ce =150 C, are conducive. A diode damageing network with diodes of attachment extent 1/20 that of the might transistors is to be used to furnish dispose AB performance.
a) What is the optimum and <(max)>?
b) if we demand that the currect through the diodes disagree by no over than a constituent of 6, what (ordinary beginning) is certain and what results?
c) Suppose that the simply might yield conducive has Vs = ±15V. VL(Max) does not attributable attributable attributable vary, and neither does the Idamage demandment. But VL(worst), PD(worst, disposeB) , and PDQ do. What are their values?
D) What is (worst,total)?
e) What extent excitement sinks are needed ce each transistor if we demand a protection margin = 25 C
