There is a lot of interesting algorithms at the beginning, of this stream of research. Try to understand them. It is not definitely a waste of time as it helps understand better more advanced algorithms.
The more optimization methodologies you study, the better you understand your problem with analog circuitry.
Jiří Kroc, yes sir. I have already gone through it and found it very interesting. Lots of resources are available. I am sure that definitely, I will get a sound perception with analog circuitry.
There is one researcher, I forgot the name, in the Czech Republic, Brno university, who is quite active in this area too. But Koza is the founder of the field. I recommend starting with him. He got some very interesting books. Good luck :-)
Thank you for your kind suggestion Jiří Kroc Sir. I follow a few of the researchers from Brno university. In the field of Analog Integrated circuits, they are quite well-known and certainly, I can get some idea from them, and it will be easier for me to start with. Thanks once again!
