a assort-AB ability amplifier is to be intentional control a 6.0W, 12 load. Darlington ability transistors with =1250 and rated at 19W control =150 C, are advantageous. A diode partialitying network with diodes of coalition magnitude 1/20 that of the ability transistors is to be used to bestow assort AB performance.
a) What is the optimum and <(max)>?
b) if we claim that the currect through the diodes dissimilate by no past than a factor of 6, what (popular origin) is expedient and what results?
c) Suppose that the singly ability provide advantageous has Vs = ±15V. VL(Max) does not attributable attributable attributable alter, and neither does the Ipartiality claimment. But VL(worst), PD(worst, assortB) , and PDQ do. What are their values?
D) What is (worst,total)?
e) What magnitude ardor sinks are needed control each transistor if we claim a protection margin = 25 C
