A simple behavioural model of the LM334 3-Terminal Adjustable Current Source.
A simple behavioural model of the LM334 3-Terminal Adjustable Current Source.
It turns on at just below 0.9V and breaks down just below 40V.
The voltage V(R)-V(N) is set for a temperature of 300degK.
The model is ideal in that it has no reverse bias behaviour and has infinite supply rejection, i.e. it's regulation is perfect.
Log plots show turn on and breakdown in the same windows. F5 to simulate.

I'm familiar with basic electronics, but... is there a primer somewhere on what these erzatz symbols mean? |

There's no specific primer. If you open the Editor and hover your mouse over each symbol in the left hand components (or elements) panel then you'll see a short description. Although CL is not spice, many of the elements, names and symbols come from the spice roots. (a) The documentation on this in CL needs improving: https://www.circuitlab.com/docs/ (b) for more esoteric devices (things like VCVS, CCCS), search CL for those names or abbreviations and play with the examples that brings up. (c) run example circuits: https://www.circuitlab.com/user/CircuitLab/ (d) put components into your own simple examples and play with things to see what they do. If you get stuck, post back into https://www.circuitlab.com/forums/support/ or https://www.circuitlab.com/forums/modeling-and-simulation/ :) |
