Project curve tracer

Thursday, June 16th, 2016

  Jason Jones has been working on a curve tracer project: As the hardware is at the point of initial release, but the firmware and GUI aren't quite there yet, I decided that it would be prudent to split off the firmware and GUI components into their own GIT repositories....

USB curve tracer for NPN transistors

Thursday, April 21st, 2016

Dilshan Jayakody documented his USB port base NPN transistor curve tracer project: Curve tracer is an electronic test instrument to analyze the characteristics of transistors and other discrete semiconductors. In this post we construct USB base curve tracer to analyze properties of NPN transistors. This curve tracer is build around Microchip's...

Yet another semiconductor V/I curve tracer – II

Tuesday, September 10th, 2013

Kerry D. Wong posted an update on his semiconductor V/I curve tracer we covered previously: In my previous post, I showed my design of a semiconductor V/I curve tracer and discussed its theory of operation in detail. As promised, I will share some of the test results here. If you have...

Yet another semiconductor V/I curve tracer – I

Tuesday, September 3rd, 2013

Kerry D. Wong writes: Semiconductor curve tracers were frequently used in analog circuit designs many decades ago, at a time when discrete semiconductor devices were in dominance and ICs were scarce. While curve tracers are no longer widely used nowadays due to the ubiquity of digital circuitry and computer aided...
