I have to design a Class AB push pull amplifier with VBE multiplier biasing and using a pnp current mirror to bias the VBE multiplier.
I am using OrCAD, with Q2N2222 and Q2N2907A βf=50 and Is=14.34f for both types of transistors.
I attached the schematic for circuit that i have so far, but it's not working, as the output at R6 only shows the bottom half of the wave and it's not really amplifying the input.
Any help is appreciated.
