Dynamic-load circuit determines a battery’s internal resistance
by Jim Williams @ end.com The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery's electrochemical condition and construction. If you attempt to use an ordinary ac...

Simple nanosecond-width pulse generator provides high performance
by Jim Williams @ edn.com If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator...

Curve Tracer Project
Jason Jones has tipped us with his latest project. He is working on a semiconductor curve tracer and details his progress on his website. I have thought about this a lot recently and - in order to get the cost down - the unit must have a cheap or available power supply and must coopt...
