hi
i have designed POR circuit which doesn't have external cap.
able to get good results for 20uA current consumption.
but i need a circuit which has to work for 2uA(without external cap).
i have seen few datasheets around ~ 2uA.in those datasheets architechture is {BG+COMP+OSC+COUNTER}. BG itself would cousume more than 2uA..
can someone give the link for an ultra low power POR circuit.
