Hi all,

Table 8.2-2 of Allenís book <<CMOS Analog Circuit Design>> gives us a procedure to design a two-stage open-loop comparator for a linear response, in step 3, there is a equation I5=I7(2CI/CII), but I really donít know how and from where can I derive it, your suggestions and time will be highly appreciated.

Rgds,
Terry
