The circumference shown uses amalgamation superbeta transistors (besides denominated the Sziklai topology).
Pretend PL(max) = 20W driving an RL = 4.5? load. Besides pretend tit conformity in the haul and haul-down transistor so that 1 = 2 = 25 and 3 = 4 = 40. Pretend that R3, R4 delight 25% of the general afar from the mean nodes of the Q1, Q2 expedite transistors (R3 , R4 acception the ON-OFF urge).
a)VL(max) and terminationing ? IS(max) ?
b) S ce each amalgamation transistor two.
c)If Ibias = 4.5mA and the general IR through R1 and R2 is elected to be 0.25mA what values termination ce quiescent levels IQ and PDQ assuming VS = VL(max)?
d)If the might accoutre is VS = ±15V what is VL(worst) and PD(worst, tot) ce the circumference ?
e) Ce segregate (d) what is the PS at VL = VL(max) and the aptitude?
