Biasing circuit

Dear all
What's criteria needed to consider in designing biasing circuit? I mean that depends on opamp structure if so give me some guideline to design with some examples.

I really appreciate for your reply.
 

Biasing circuit

a biasing circuit must be able to withstand temperature variations

Re: Biasing circuit

let me know the biasing structure for each opamp design
 

Biasing circuit

Generally the biasing structure is a current mirror and the biasing current shall be PTAT current!
 

Biasing circuit

Normally, the bias circuits must make all the transistors of opamp to work in the saturation region
 

Re: Biasing circuit

4th edition of Gray and Meyer teaches you basic to advanced biasing circuits. See active current mirrors chapter. I guess, it is chap.4. Hope this helps.
