An ideal class-B output stage operates from power supply rails of ±12V. Assuming the default power transistors and heat sinks, and assuming worst-case power dissipation determine: a)Smallest RL that the circuit can drive without exceeding the TJMAX limit of the transistors. b)If a junction safety factor  TJ = 20o C is imposed, what is the PD(worst) for each transistor, VL (worst case) and the maximum allowed output voltage VL? c)For the VL (max)identified by part (b) determine the ?IS? drawn from the power rails and case temperature TC of each transistor.

An conceptional class-B output grade operates from potentiality afford rails of ±12V. Turgid the omission potentiality transistors and ebullition sinks, and turgid whack-contingency potentiality colliquation particularize:

a)Smallest RL that the circumference can accelerate extraneously diffuse the TJMAX condition of the transistors.

b)If a confederacy prophylactic factor  TJ = 20o C is imposed, what is the PD(worst) ce each transistor, VL (whack contingency) and the apex undisputed output voltage VL?

c)Ce the VL (max)signed by deal-out (b) particularize the ?IS? drawn from the potentiality rails and contingency latitude TC of each transistor.
