I have made some research for a pcb coil design. Before designing the pcb I took some measurements for the coil. Using a 0.25mm wire I made a winding with these results:
148mm x 100mm / 42 turns
12.8Ohm / 770uH
Now I need to design a pcb coil with the same characteristics. Using the same distances/turns (2 or 4 layers pcb) could I have the same results (~770uH)? If yes, how much must be the track's thickness in order to take the same resistance (~12.8Ohm) with the 0.25mm wire?
