design rectangular spiral inductor
I have used the ADS rectangular inductor smart component to design an inductor. after using the passive circuit design guide.. i have used the design in the layout with the rest of the circuit. now the problem is a spiral inducotr is usually designed with 2 metal layers in substrate definiton...and a via which i am not sure how do define. so how do i do that with this inductor that I defiend using the smart component. and howdo I calculate the dimensions of the metal from the centre to the next component i.e. a 50 Ω line and the outermost turn to the previous component i.e. a radial stub representing a capacitor. If someone could also clarify what layers are to be deifned and how...and which connecting line is to be placed on which layer I'd be very grateful. thnx...
