doin OK, trying to write a paper on a high feedback technique, so i
shouldn't be spending as much time as i do on these forums
Trying to communicate engineering concepts without local graphics storage seems a major handicap in your thread and this forum
buffers with simple topologies are hard to compare when the feedback is affected by the bilateral nature of the devices - input impedance has a quite noticeable effect on emitter follower/Darlington/Szilkai performance
just downloaded the Linear Technology SwCad III to post sims over on DIYaudio.com - i'm quite impressed after < 1 week
