Can anyone tell me how to do constant current
biasing for integrated circuit amplifiers. I would perfer a reference
or something. I'm sure there are different ways you can do it and i
would like to see how they're done. While we're at it, also how to do
constant Vbe biasing but not the standard resistive divider way. Current
mirror won't because I can't bias my emitter because of swing issues.
Thanks a lot.

Yes there is more than one way to bias an amplifier.
Here is an application note, which can be useful for your question:
