Hey guys, I'm designing a wireless cell phone charger that can be used inside a car for the senior design project. I'm feeding 12V DC into a colpitts oscillator which is fed into a B class power amplifier which will then be fed into the transmitting coil. Each one works great independently but when I connect them together, the voltage swing is off. It goes from about +4V to -8V and I would prefer it to be +6V to -6V. Also, the peak voltages cut off... I'm guessing from the fact that the input voltage is the same DC input that the transistors run off. What is wrong with the circuit? I attached the schematic as well as the output (and a zoomed in output). Q1 is a general purpose BJT (2N2222) Thanks for the help!
