The third answer in the linked stack exchange post suggests that it might be possible to make a latch with one transistor .The idea is that logic values are represented by presence or absence of a specific frequency oscillation instead a high or low voltage.
Is this actually possible? If it is, can you build digital logic based on this technique. Can it be simpler than conventional transistor transistor logic?
This would be similar to "code golf" where you try to write the shortest program to do something.
Probably a quixotic search, but I think I'll learn a lot about transistor math in the process.
A separate project that is interesting to me is to make a microprocessor with a minimal number of transistors. Wikipedia says that an 8080 has about 4500 transistors. Can that be substantially decreased? If you take out some of the features like interrupts and BCD is it possible to use fewer (performance be damned).
I was researching early computer technology and found references to a circuit used by some Japanese systems called the Parametron https://en.wikipedia.org/wiki/Parametron It resembles some of my ideas for this circuit. I had been thinking that the circuit would represent 1 vs. 0 by the phase of an oscillating signal with 180 degrees apart would be the 1 and 0 values.
One advantage of the parametron design was that it was more reliable than early transistors.
This is one possible waveform for voltage on the latch's main capacitor. The idea is that the high (red) and low (blue) values are 180° out of phase from each other. The power signal provides the concept of phase.
There has to be at least an additional capacitor or inductor to distinguish the state when the two waveforms cross each other.
[I put this in description instead of project log. moving it here]
While brainstorming, I thought of a potential implementation. The signals would oscillations 180 degrees out of phase to represent zero and one instead of yes oscillation/no oscillation.
Another brainstorming idea is to make the power supply oscillate at twice the speed of the data's oscillation. Most probably the polarity of the supply wouldn't go from + to - . Instead it would be offset from zero by a volt or two. For example, Peak to peak might between 1V and 4V.
