What does the whole concepts of Circuit Design entails ?

I'm currently at a point where I need decide which online course I need take to build power efficient circuit ; understanding the principles of power efficient circuits and what it takes to venture into it.

While power loss in electronic circuits isn't evitable, there are certain amount of undesirable power loss which unnecessarily reduce circuit efficiency thereby reducing battery life.


I know Low power devices (LDO) exist and Power Electronics might just be what anyone would have easily suggested, but I'd like to know if having the knowledge of circuit design would be an essential ingredients as well ? If yes, back to my question at the top what does the whole concept of circuit design truly entails ?

Ps: I need get real answers from expertise which is the reason I've intentionally made this post here, the internet is full of all sort of answers from unknown authors, one might get confused or lost trying to get answer to a problem.


Thanks Forum, anticipate your answers .

 

Your head is in a very dark place, and you need to remove it from that place as soon as possible. Power loss in all electronic circuits is in fact inevitable. No single course can equip you for what you seem to desire. The process of becoming a competent circuit designer is a slow and arduous one. It takes patience, dedication, and attention to detail. What it truly entails is developing an understanding of how individual components behave in isolation and in combination with other components. There are no easy shortcuts or simple answers. It may take a decade and a half before you achieve even a modest level of capability.

 

An online course, (or even several) is unlikely to give you the expertise you need for power efficient (or any kind) of circuits.
As PB noted, that will take several years of learning, plus several more of experience before you even get close to that point.
Certainly you can't design power efficient circuits without knowing how to design circuits.

For example an LDO is not necessarily a low power circuit, it refers to a Low-Drop-Out linear regulator.

 

OTOH you can become an esthetician in six months. I know because I paid for my granddaughter to become one.
