I'm an electronic engineer, I have teaching experience and very good materials about BJTs, MOSFETs and FETs. I can provide you with a report on BJT amp which may contains:
- Theory of operation
- History of BJTs
- Design considerations
- Main applications
- Single Amplifier with BJT
- Power Audio Amplifier with BJT
- Current Amplifier with with BJT
If you have an special subject to develop, please PM with more info.
