analog and digital circuit

[Alex QW]

Hi all,

I am a newbie in designing analog and digital circuits and I always find that hard and no idea to start designing digital and analog circuits from scratch
Any solution or suggestions to improve my analog and digital designing skills?

break what your trying to do into small blocks,then google (other search engines available) those small blocks and steel use the results as inspiration for your design.

Serious suggestion:  first start by defining the function of the circuit you want to design.
If it is an amplifier, you should define the gain (e.g., voltage gain), expected input voltage range, bandwidth (including down to DC, if necessary, or low-frequency response for AC amplifier).
Further requirements include input impedance, output current capability, etc.
These are all quantitative:  you can apply them to basic circuits found in textbooks to get what you need.

Have you specified, designed, implemeted, and tested something other that analogue and digital circuits? If so, use the same processes.

What experience do you have with analogue and digital circuits?

Hi TimFox,

Should I read back all the fundamental theories of digital and analog electronics I feel that my fundamentals are not strong enough but doing it in this way will be time-consuming

It never hurts to review the fundamentals.
If you are in a hurry, go to one of the "cookbook" style books, find a basic circuit, and apply my suggestion to impose your quantitative design requirements on it.

Hi Timfox,

May I know what is a cookbook?

Examples:  W G Jung:  "IC Op-Amp Cookbook" (1974).  https://www.milanmedia.pro/ic-op-amp-cookbook-by-walter-g-jung/  for a pirated PDF.

Hi Timfox,

IS this book a cookbook (Introductory Circuit Analysis by Boylestad)

No, that's a textbook.
"Cookbooks", in this context, are books showing examples of working circuits with short discussions of details.
The Jung book I mentioned is perhaps the first book to use that term.
"Textbooks" cover the subject from first principles.
Both are useful.
