Input voltage is 500mV rms. Image source: Electronics Tutorials - Class AB Amplifier Driver Stage This is what I have done so far CALCULATIONS. R_L = 8 Ω P_AVG = 10W Bandwidth from 20 Hz to 18 kHz V_ (0 peak) = √ (2×10×8) = 12.65v V_CC = V_ (0 peak)×2+2 = 27.3V ≅ 28V I_ (0 peak) = V_ (0 peak)/R_L = 12.65/8 = 1.58A

Basic Class AB Amplifier Circuit 1. Bias Q N and Q P into slight conduction (fwd. act.) when v I = 0: i N = i P. 2 Ideally Q N and Q P are: a. Matched (unlikely with discrete transistors and challenging in IC). b. Operate at same ambient temperature. NOTE. This is base-voltage biasing with all its stability problems! i L=i N −i P 3.For v i > 0: i N > i P i.e. Q N

Fig 5.5.3 Class AB Output Stage Operation Tr1 driver transistor is a class A voltage amplifier fed with a variable amplitude audio signal from the input via the volume control VR1. Bias for Tr1 is provided via the potential divider R2, Vr2 & R3 from the junction of Tr2 & Tr3 emitters, which will be at half of the supply voltage.

So I need to calculate quiescent points of both transistors, current gain, voltage gain, output resistance input resistance and the efficiency of a diode biased class AB power amp. Now ... if you ignore Ib1 and Ib2 the diode currents should be (Vcc-0,6)/R3 (2mA in my case). UceQ1=UceQ2=Ucc IcQ1 and IcQ2 I tried calculating like this: Ud1+Ud2=Ube1+Ueb2
