Hi All,
Circuit:
Result(LED current, change V2 from 0V to 2.4V) :
I wish Q62 consume lower current, but it will effect LED current.
I hope LED current can larger than 10mA ( due to small beta of Q64 when variation ) I wish consume less than 30uA in Q62, does it possible?
It seems that I can't use FET here, because the Vto almost
3.0V........... it is hard to drive... in my application, I have only 2.4V and 2.8V supply, am I right?Best regards, Boki.
