Recently, I'm drawing the inductor in the layout. My procedure to do this is, first drawing a ring, second convert it to polygon. But I find it is not very convenient since after you convert the ring into the polygon the width of the metal can't be changed.
Could someone know how to solve this? Or is there any other better procedure to draw an inductor and transformer?
Thanks in advance~~~
Sorry to make you confused.
"ring" I mean my first step is to draw a ring, a circle.(in Cadence layout window, under the menu EDIT). Then I draw the second ring which has larger diameter, and erase some of them. Finally I connect them where I earse, thus making a two turns of spiral Ind.
