the value of my coil (spiral inductor) is very high. due to this, I would like to reduce the size of the coil by replacing it with multiple coils connected in series. my PCB board has 6 layers. each layer from layer 2 onwards will have a coil and all of them will be connected together with a via (series connection). i dont have any coil on the Top layer.
the problem with ADS is, coil need MSUB definition which needs a ground plane underneath. how do I define my series coil connection in 5 layers as above? does each coil treat the coil below it as a ground plane ? or shall I state H (substrate thickness) as a infinite number since there is actually no ground plane underneath these coils, its just the next coil.
