Dear All,
I want to design an IC spiral inductor (using TSMC 0.18um CMOS Technology).
I found the spiral inductors of the technology has the spiral inductor(M6 "Blue") and its ground plane (M1 "Green ring"), so I want to mimic this behaviour in my own inductor, as illustrated in the following screenshot.
According this configuration, How I can determine the correct ports, Should I use diffrential ports (+ve for the M6 and the -ve for the M1)?
if I use this, the generated inductance due to the ground plane (M1 Ring) will be added to the simulated inductance.
i found another design of spiral inductor without using ground plane, as described in the following screenshot M6 "Blue" and M5 "seems like Orange" .
Should I use a single ports for this shape?
what is the difference between the two desogns with and without the ground plane?
in my layout, How i can use these two designs?
Thanks in advance
