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.
