COX is a critical design parameter for CMOS design. It is the capacitance generated by the gate oxide capacitance and is a parameter that generates the transconductance gain number for the MOSFET. A calculator for this parameter was posted by the team at Signal Processing Group Inc. to facilitate the designer’s task of designing CMOS circuits. It can be found under the “calculators” menu item on the SPG website.
Complex and absolute numbers are used extensively in RFMW design. A design engineer should be conversant with these quantities and their conversions and manipulations for effective analysis. A recently released “cheat-sheet” for complex and absolute numbers has been released by Signal Processing Group Inc. and is available on the SPG website. Please find the link under “complementary” items. Please visit the SPG website for technical info and other items of interest.
