thanks,but I will not use a battery,my goal is to design such a voltage source,and the voltage regulator may be the suitable one.srizbf said:a 'voltage regulator' is classic example of
constant voltage source.
(or) ,
a battery (within its discharge rating ) is another one.

nope, it should be an constant voltage source ignoring its current.calculus_cuthbert said:are you talking about a voltage controlled current source?
yes,the voltage regulator.srhoar said:For it to be a constant voltage source, it has to be able to supply different currents.
If the load on the driver changes, then the current must change.
Voltage
-------- = current

Just put a zener diode across the source.

Thanks,your answer is helpful.Please also pay attention to the attachment,is it possible to fix the Vx to a constant value without using a bandgap and voltage regulator(because it is a part of a bandgap circuit) as the vdd changes from 2v to 5v.------I hope have disccribed the question distinctly.keith1200rs said:Voltage regulators are designed to supply a significant current - up to several amps at a constant voltage, a bandgap will provide a more stable voltage than a regulator over temperature, but only up to a few mA. A bandgap is one element of a voltage regulator.
