A transistor has a β of 150 and is emitter biased with RE = 1.5kΩ, VCC = 15V, and RB = 220kΩ. If VBE = 0.7V, calculate the base current, collector current, and the collector-emitter voltage VCE. Discuss the expected stability.
💡 Hint: Don't forget to account for the feedback effect from RE on base current.
Design an emitter bias configuration to achieve a Q-point of IC = 2 mA, VCE = 10V with VCC = 12V. List the resistor values you would choose and justify your choice based on stability.
💡 Hint: Consider how feedback from RE helps achieve desired values.
