QUESTION 6: A simplified class-AB output stage with BJTs is shown below. The circuit parameters are VCC = 23 V and RL = 1800 Ω. For each transistor, IS = 8×10−15 A. Currents iCn = iCp = 1 mA when vl = 0. For vO = −4.8 V, determine iL, iCn, iCp, and vl. What is the power dissipated in Qn, Qp, and RL? iL (mA) iCn (mA), iCp (mA), and vl (V) PQn (mW) PQp (mW) PRL (mW) format :
