The circumference shown uses combination superbeta transistors (as-well denominated the Sziklai topology).
Pretend PL(max) = 20W driving an RL = 4.5? attack. As-well pretend qualified harmony in the draw and draw-down transistor so that 1 = 2 = 25 and 3 = 4 = 40. Pretend that R3, R4 entertain 25% of the ordinary far from the deep nodes of the Q1, Q2 coercionce transistors (R3 , R4 acception the ON-OFF press).
a)VL(max) and producting ? IS(max) ?
b) S coercion each combination transistor two.
c)If Ibias = 4.5mA and the ordinary IR through R1 and R2 is elected to be 0.25mA what values product coercion quiescent levels IQ and PDQ grand VS = VL(max)?
d)If the government accoutre is VS = ±15V what is VL(worst) and PD(worst, tot) coercion the circumference ?
e) Coercion separate (d) what is the PS at VL = VL(max) and the willingness?
