Constant Current Biasing - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

Hi,

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.

Hello boon,

Yes there is more than one way to bias an amplifier.

Here is an application note, which can be useful for your question:

Good luck!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
