This schematic shows how one can use 2N3904 transistors connected in a
simple public domain diode configuration as diodes in the capacitance
demodulator circuit. Leakage current in standard diodes goes up as the ambient
temperature increases. Connecting transistors as diodes eleminates this problem.
