Printed Coil
Printed Coil
(OP)
Hello,
I have a great problem with the design of an printed coil.
I want to design a 130nH coil on a PCB but I have
2 different Formulas to calculate the inductivity.
So I´m not really sure which formula I should use.
I hope somebody knows a solution for my problem.
Any advice would be greatly appreciated.

PC Inductors are frequently non-ideal. Due to the distributed parsitic capacitance and low-inductance-per-unit-length of trace, PC inductors have Q problems, and may try to act like a transmission line stub in your circuit. However, for cost savings reasons, PC inductors frequently show up in circuits, and some RF software programs allow you to model them. As Melone points out, tolerance repeatability is also a problem.

a normal Coil in a 0603 Package it´s smaller and
not so complicated.
