Does anybody know about this? I don't need a very accurate current, maybe ±5% is OK.
Thanks !

±5% is enoughkwkam said:It depends on how accurate of your on chip device.
prcken said:i dont think you can do that with internal resistors, variation of internal resistors would be more than 30%!
maybe you could only use trimming, maybe you could switched capacitors to realize the resistor, refer to fig 11.22 of Razavi's design of analog CMOS IC book.

an oscillator to make isnt a problem nowadays_even, as onchip type too...
