Are you actually incapable of designing an original circuit that you
are confident will work?
As I have explained many times. The only way to achieve something truly
new is for that newness to be achieved by randomness. If it is random,
by definition, it operation can not be predicted with certainty.
Of course, I have designed many circuits that are "novel" by combining
existing circuits (cross coupled genes) that have worked 1st time. In
these case one can make a prediction based on existing knowledge.
I do that all the time. I dislike copying
circuits, even my own.
You still dont get the point. Its strickly imposible to design a "new"
circuit without copying something. Again, I have already explained, that
one must use *existing* knowledge (i.e. copying) to produce a usefull
design, for example, one will use diff pairs, current mirrors, cascodes,
push-pull outputs, salen-key filter, etc.
To obtain a totally original circuit you must use a pifetz, connected to
wizbangs, driven by gottenburgs, and you no can't connect them up with
wire, thats already been done, so not orginal.
Tell, when and how did you manage to invent these new physics
components?
Sometimes I do a little math, sometimes even
use a calculator, and sometimes sketch a Bode plot or such to check
closed-loop stability. Simulation is reserved for just the rare,
really hardcore cases.
You are not doing complex analogue designs then. Its that simple.
I think you are not being honest with yourself, or simply not
understanding what it is you actually do or what I am saying.
