i agree, it's not a good idea: depending on the placing of inverters and routing of connections the period of a ring oscillator can change up to 50-60% on the same board. I suppose you don't want to use complicated PLL/DLL architectures to control the period
diff b/w electronics and electrical
you can think about electrics as circuits which transfer and manipulate energy, whereas electronics are circuits which manipulate signals (information). of course the difference is not that hard, because these two terms come out from hystorical reasons
Re: "Active" or "Passive" filter in PLL
my 2 cents:
for what i know PLL is one of those designs that prefer passive filters. That's because just after the filter you have the VCO. On the imput of the VCO you would like to have the most possible constant value (no oscillations at all neither...
eye diagram simulation
they're two effects of the same phenomenon. Suppose to have a periodic waveform. Due to several noise sources the period won't be exactly the same at each cycle. For this reason if you analize the waveform in the frequency domain you won't see lines, but lorenz-like...
Just some thought:
seems many people are working to reach the fotonic era, but many problems are yet to solve. For what i've understood the main problems are about the possibility to integrate optic circuits on the same chip: different optic devices are nowadays realized on different...
