What do you think about this ampliffier? yes, I know the power step, class AB, has not polarization (but whit multisim an error occurs if I place the polarization diodes)
This is the output signal (for me it's allmost rail to rail :shock
and this is the bandwidth
Until now it had never been possible to obtain a great voltage gain to exite the power stage.
But seeing the TL082's schematic I realized that there were current sources. So there I realized that the current source allowed me to have a proper polarization and have a high impedance collector, hoe.
I make it only whit BC548 because it's cheaper and easy to find and for the power stage I'm going to use 2SC5200 and 2SC1943.
The signal distortion I think it's for the software simulations.
And this it's the proteus simulation
Why the higher the gain less resistance, in the resistances of the polarization of the power stage?
