Talk:NMOS self-biased cascoded current mirror

There are a couple of iterations that will be needed here
 * This may require a bit of expected up-sizing of the cascode device, to allow sufficient headroom for the mirror devices
 * Mirror devices may need to be made thinner (but perhaps not necessary) to allow a larger headroom for the branch (no necessarily since the vdsat of the mirrors will get increased).
 * Need to find a way to compare fairly with other mirrors
