Question

2) VBE Multiplier: For the following Class AB amplifier, transistor Q3, RI and R2 create a VBE multiplier to bias the push-pull circuit of Q1 and Q2. Answer the following knowing that: Transistor Parameters: β large (all transistors) Q1 and Q2 matched Isl = 1s2 = 1.0 x 10'14 A 153 = 1.0 x 10-15 A (Don't assume that VBEON +10V BIAS 0.7 VDC) R1 03 Biasing Parameters: VBB O Vout 10KS2 Vout, DC 0 VDC R2 = 1.338 VDC A) Find Ici and Ic B) For VBES-0.6 VDC, find R1 and R2 C) Find the total Power (mW), PsToraL, delivered by Q2 IDc DC Vin 10VO the two power supplies (+/-10V). D) What is Voc for this circuit?
