Python - command line SPICE interface and plotting

GNUcap or NGspice voltage multiplier sim.

Used for my Ph.D. qualifying exam, and a follow-on to my harmonic radar tag improvements.

NOTE: Consider using PySpice instead of this approach.

Installation:

• Linux: apt install ngspice
• macOS: brew install ngspice
• Windows

Simulate no-driver Cree XHP LED problems due to wire voltage drop, using ledDrop.net and io.StringIO to avoid output file mess.

python ledDrop.py

Other programs

These programs run from GNU Octave or Matlab.

• runDub.m run and plot basic voltage doubler current input and voltage output vs. time
• runDubTry.m plot spectrum
• runDubMult.m multi-stage voltage multiplier: voltage, current, impedance
• runMos.m using MOS simulation
