We are going to starting a design house in Jiaxing next to Shanghai.
The Corp. will focus on li-battery application.
I am Tony, used to work at Fairchild, graduated from SEU.

I = V/R, V constant, R(i.e. LEDs) constant, how can I vary?!
You may need a fast transient DCDC to step its output between e.g. 1V (LED off) and 3V(LED on).

We are a team good at power and battery management IC/IP design.

Diarmuid,
Then the bias voltage will have larger variation over fs or sf corner.
It means in order to keep the non-cascode MOS in saturation, the output range will be narrower.

Assuming the ref voltage large enough.
I think the ref voltage should as close to the full scale as possible.
Because the larger the input signal value comparing to the ref, the higher SNR.
Hi,
Step 1, find out or define the min OCM(output common) voltage;
Step 2, apply this min OCM to the gate in your attached SCH;
Step 3, SIM it with width swept at max load, and ss corner, and hot temp;
Step 4, find the width that VDD - VOUT < specified dropout in the SIM result.
Hi,
With only 5uA current, I believe your bandgap wont drive large RES/CAP load.
So either two stage miller opamp or folded cascode opamp should be OK
Come on! Design it first.
Hi,
In HSPICE, we use variation block to define the input parameter, including std. (sigma) and ...
When monte carlo analysis is performed, the sigma parameter has nothing to do with the sim output.
Which means you have to do the statistics yourself.
