Dear all,
I'm searching a comparator topology suitable to work with a maximum total budget current of 100nA.
As the current budget is really low, I was wondering if it exist a topology that allows me to obtain a short delay time.
The maximum tolerable delay has to be 1us, with an over voltage of 5mV (Vin - Vref).
Actually what I have implemented is a simple cross-coupled comparator(positive feedback with hysteresis), but as I expected, I cannot achieve the spec.
Do you have any suggestions for me?
Kindest Regards
