Variable Capacitance using Diodes.pdf

I wrote this document to explain the use of standard diodes in varicap mode -

Much of what is here was posted on the

"Capacitance from diodes" thread on Theremin world.

and the preceding thread Waveshape,Timbre,etc:

This document details the principle, shows some test results, presents schematics, gives circuit for thermal compensation -

Everything needed to use diodes as voltage controlled capacitors.
