Introduction   This is a follow-up to A Transistor Load which I blogged about as part of the Project14 Test and Instrumentation competition. Since then I've been looking at the way the load performs, so this blog is on the subject of stability. By 'stability', I mean not only whether there's the possibility of the circuit breaking into sustained oscillations, but whether we might be close to that and the waveforms might ring badly (damped oscillations). To do this, I'm going to use th ...
