I want to create a PCB Coil to attach to a channel on my LDC1614, but my school teacher said our tools only have the capability of making single-layer coils. WEBENCH says it can only export 2 and 4 layer coils. How do I get a CAD export for a single layer coil? Also, does TI independently sell PCB coils such as the ones that come with the LDC1614 evaluation board?
Kylie,
You can analyse and design a single layer coil using WEBENCH Coil Designer. While exporting from WEBENCH Coil Designer you can increase a layer and make it 2 layer. Once you have exported the PCB layout you can delete the second layer. Since there is only one layer you need to use a wire (jumper) to make connection in the center.
Here is a link to single layer coil design. Please note the performance parameters for single layer coil as shown in the right side of the snapshot.
When you want to export, increase the layer to 2. Here is the link to 2-layer design. You can see that performance parameters of coil have changed in below snapshot.
When you delete a layer, you can get the coil performance parameters of single layer as you designed.
