I have attached circuit and I am gonna run simulation. Before running simulation, transistors should be correctly sized to get the output.
I know how to size M5, M6 and M7 transistors in the figure, but the problem once having a voltage doubler (M1-M4 transistors). This voltage doubler affects all sizing and some design rules should be taken into consideration.
what kind of procedure that I can follow to size them.
without voltage doubler: M5=M7 and they have larger size ( e.g. 10500um/0.18um)
Normal voltage doubler: M1,M2=50u/0.18um
My question is that what ratios of M1/M5, M1/M6, M2/M5 and M2/M6 should be.
