nxing said:What's the meaning of "4 bias voltages"? Do you mean four independent voltages? if it is, you can just use regulator or bandgap.
ambreesh said:Hi holddreams,
Are these bias voltages used as reference in your system, if yes. Then buffer the BGR output and source a current through a resistor ladder, get your references.
yes, i want it that way.
Can you send me a paper about this?
Or can you draw a configure as you said?
Also another question, if use a resistor ladder,does the temperature have a little effect on the whole circuit?
