quad-capacitor

Quad (4-layer) capacitor

This is a design of a quad-layer capacitor, meaning that when this design is fabricated on a four-layer printed circuit board (PCB), there will be eight capacitor plates (two per layer) creating a dielectric field between the traces within a single layer and between the traces across layers.

Parametric design

In this design, plate wires can be created with varying trace widths, gaps between traces, and overall size of the board. As a result, this parametric design could theoretically be used for capacitors of any manufacturable size (from microscopic on up).

This shows the various layers on a 100mm x 100mm PCB:

Example capacitors

In this section, we will document emperically-measured capacitances as they become available.

Capacitor 1

Capacitor 1 uses a 1.6mm PCB with 0.15mm traces and measures 6229pF.

Enjoy!
