Simple common-emitter amp - Part 3

01:23:36

This circuit is more or less the same as the previous with the addition of an emitter follower (common-collector) output buffer which allows it to drive a load or another amplifier stage.
The emitter follower is biased around 5.7V DC to allow for maximum voltage swing.

I think these have been good example circuits- and I haven't seen anyone give you credit for them yet. Your layout is clean and tidy, and that makes it a lot easier to follow along and study what's happening. Many here have posted amplifier circuits, good ones too- but I have yet to see a suitable explanation of operation that matches the complexity of the given example. I do understand though that would take a bit of writing! The examples you've been posting are the building blocks of Class A amplifier topologies, and something I think everyone would do well to learn and understand. So I say- good job, keep it up! =^>

Thank you, I always try my best to give a good explanation of my circuits without using too much math, if anyone has question I can be contacted on Skype: james-wood-uk

HI. You should only change 2 switches that connect both generators to only one switch with 2 positions because if we turn on both switches it gives error and we have to get out of the circuit to restart it. Rest is fine.

Fixed.
