A Transistor Load A Transistor Load: Stability A Transistor Load: Stability Part 2   Introduction   Important note: I'm learning about design with transistors and this is an investigation of transistor design techniques and presents a first prototype of a possible circuit, it's a long way from being a finished project suitable for replication.   I said in the original blog that I'd explain how I arrived at the design, so in this blog I'm going to give a quick run- throu ...
Introduction   This is a short follow-up to A Transistor Load which I blogged about as part of the Project14 Test and Instrumentation competition.   In the last blog A Transistor Load: Stability I got as far as compensating the amplifier section with a single 'dominant pole' capacitor and looking at the way the dynamic response was affected by different capacitor values. I also looked at the issue of lead inductance in the output current loop. I've done a little bit more work on ...
