Small Signal Diodes. Voltages are in Volts, currents in Amps.
This program is written for use with calculators using Reverse Polish
Notation and having an 'Equation Solver', such as the Hewlett Packard
model 32S or 35s. It uses only two diode forward voltage/current pairs.
For simplicity, the voltage drop in the bulk series resistance of the diode is assumed to be zero. This is a good assumption for most detector diodes when the current is below a few uA.
Two diode forward current pairs are used: Vd1 (the higher voltage)=V, Id1 (the higher current)=I, Vd2 (the lower voltage)=U and Id2 (the lower current)=J. (Is) and (n) are calculated at an equivalent actual diode forward current of 4-5 times (Is) if the voltages of the two voltage/current pairs are: V=0.055 and U=0.039 volts. The orange colored shift key is represented by '#'
