The times were 1970s and 1980s when the students thought that mathematics and simple digital logic looked better than the differential functions that used to describe certain analog properties: a time when they probably didn’t have access to the fun of free electronics videos. The twin Ms – monolithic memories and microprocessors took hold of headlines. They were ruling the world and started converting nearly all the academic and commercial electronics into digital paradigm.
This digitization also escorted the increase of digital signal processing. This is the idea that everything must be converted from analog to digital as soon as possible and also must be processed in the digital domain for longer before being converted back to analog to compel a kind of exhibition, and speaker or actuator as well.
Nevertheless, in those days the matter of energy consumption typically was not the first thing people consider about. Nowadays, it is one of the pivotal concerns worldwide. And who can say that it is more acceptable to be extravagant with digital transistor hacks. And this caused a return to using more analog circuit or a move to neuromorphic computing style. Now, with increasing global competition in the context of financial limitations of digital electronics, especially when it is about the consumers, the digital world has become a ground less attractive to play on.
Thus, some companies started drifting towards analog. For them MEMS and sensors were the places to survive. But there was no place to be satisfied. Competition is coming with full vigor as it was in the period of digital province. We are in all probability in a phase of analog supremacy, at the same place where digital was in the 1990s and 2000s.
