Current Compliance or Current Starvation?

[engrMunna]

Hi,
I tried reading about current compliance and current starvation....but I couldn't really understand..I mean both methods are use to limit the current to a load. So does this mean that if I have resistive load of say 1Kohm, and I apply a voltage of 1V across it then Current Compliance or current starvation can limit the current flowing through the load. Say that with a 1 V across the 1Kohm load, I get a maximum current of 1uA flowing through the load?

to add to the post, is there any such method which limits the current but allows the voltage to increase across a resistor?

No replies let me change my question a bit,
1. Can some one explain what is current compliance?
2. Ref. to the figure, if I have load R, and I set Vg, such that the maximum current that can flow through the mosfet is 1mA then this mean I have provided a current compliance of 1mA to the load? Is that right?

I understand Current Compliance as the ratio of a current mirror's slave current to its master current, i.e. how well the slave current complies with its master's.

Current Starvation, however, I'd associate with a resistor between emitter (or source) and GND, which straightens and limits the current through a transistor stage, so increasing its linearity (at the cost of gain).
