Hi Guys
The circuit below shows an inverting op amp with a gain of 10 and an input of 0.5V ac at 1KHz.
Therefore at point X we should be getting 5V and at point Y, 4.3V becasue of the volt drop across the emitter base.
The problem with this circuit is that cross over distortion is formed when the output is les than 0.7V.
If i connect point X to point Y which will result the output being part of the feedback loop what is the likely output voltage going to be? How do i figure out what amount of voltage is fed back into the op amp input?.
I cant seem to work out the math to calculte this.
Yes this is homework but i dont understand how the feeback bit can be predicted with maths like i have with no feedback connection.
any help is more than welcome
thank you
andy
