A question which I’ve been asked was, ‘Is modern Electronics fundamentally new?’ And the answer to that question is neither a simple Yes nor a simple No.
The theories that define how electronic circuits behave are such, that they have basically not changed in half a century. But, ever-more complex circuits have been designed, which therefore also embody some amount of creativity. This has been assisted by the facts, that:
- Integrated Circuits – aka Chips – can now be mass-produced, that contain 1000, 10000, 100000, or even 1000000 transistors, grown out of a single crystal.
- New types of components have been designed, which operate at higher voltages than before, lower voltages than before, higher frequencies than before, or with less current than before.
But the mere fact that circuit theory still is what it is, leads to the result that still, circuits can be simulated.
(Update 7/3/2019, 17h35 : )
I should acknowledge the fact that the new types of components that have been invented in the past half a century, don’t just extend the frequency range, etc. They also define new component behaviour, with Math that defines currents as flowing, as a different function of voltages, and as a new function of the rate, with which some of the voltages are changing…
But then the result is that when components are put into a circuit, separately from each component having new transfer functions, ‘the glue that connects them’ is still what it was in 1950.
