Since semiconductors aren't passive components, can I realistically derive analytic solutions for a circuit with BJTs? I know this may seem like a very naive question, but am I on the right track with this sort of analysis, or do I need more powerful numerical modelling even for basic circuits? e.g., the responses for single transistor amplifiers, etc.
I'm trying to teach myself more about circuit analysis - but after the 'RLC' passives, I don't want to end up on the wrong track. I understand this is bordering on opinions, but I really want to start on the right track.
I should mention, I've used 'rule-of-thumb' stuff for constant current, biasing etc. But I'm not entirely satisfied with this approach.
Thanks for the current (ha ha) feedback. Using some of the 'hobbyist' rules of thumb, I've found it easy to achieve switching (saturation) modes, and biasing giving consistent results with different small-signal transistors - which seemed counter intuitive and really surprised me! I really need something like a first-principles primer that doesn't gloss over the complexity, or the range of uses. My multimeter isn't teaching me much...
