This sheet is used to calculate the capacitance obtained from Lee,The Design of CMOS Radio-Frequency Integrated Circuits
The Area (A) = W * L
H
Conventional
Yuan's Formula
Sakurai's Formula
Meijs & Fokkema Formula
This graph shows the capacitance for a 200um long track, spaced 15um above the ground and of various widths
These two graphs are for different track thicknesses and are not as close in agreement as I was expecting!!!
