Hi all,
quick folded cascode question. Looking at some lectures slides, I stumbled upon the following slide/requirement:
It's the first comment. What would be the reason that I4 & I5 has to be 1.2 - 1.5 times I3? In other designs I noticed that they are mostly equal, I4=I5=I3. Also does the same rule apply for the differential PMOS variant?
Thanks in advance.
