New video: basics of the VBE Multiplier circuit
« on: March 20, 2015, 10:30:07 pm »
The video briefly describes what it is, and demonstrates how it works, and shows a typical application or two, including using it to adjust the bias point of a push-pull output stage.

I always learn something new from your videos, Alan!  I've never seen this particular circuit before.

Keep up the good work.

I would love to see you make a video on op amp compensation.

Awesome video! I read about the Vbe multiplier in an article about the 7805 (http://www.righto.com/2014/09/reverse-engineering-counterfeit-7805.html) but I didn't understand it much back then...
It was related to the bandgap reference, do you think you can make a video about that?
thanks!

Wish I saw this when I had to make my audio amplifier for school!

Great video Alan.

Somehow I had developed that circuit/copied from schematics online in designing a push/pull amplifier front end for a function generator. Your video filled in the blanks to my understanding of the circuit very well, and that is greatly appreciated.

Keep it up!
