Title: Basics for a Digital engineer to design analog Ckt
Post by kumar on Feb 28^th, 2010, 1:56am

Hi all,
I am basically from digital background. But now I have shifted to analog circuit design. Can anyone suggest me tutorials and other stuff which could help me in designing analog ckts. I have already read many analog books (allen, John & Martin ..etc). I am very good in theoretical approach.. But when coming to designing a real ckt, I am not fully confident. Please some books r tutorials which explain more in practical aspects.

hi kumar...

the best way, what i feel, is that try some simulations with a basic simulator such as LTSpice or any other tool you are comfortable with.
start with designing basic amplifier topologies such as CS, CG and try to gain some intuition about the circuit before you actually put down the values. i think allen hollberg's book would be a good one to begin with.

good luck.....

Since you've already read a lot of books and your confident about the theory part, do you think another book is going to help? Try designing an op-amp with feedback (maybe a simple low-pass filter). That should give you a good starting point.

cheers,
Aaron

@aaron_do - You have got me wrong. I can design all the building blocks stand alone. eg an amplifier, filter, etc. But when it comes to a complete system i feel difficult. For instance which is better to use as feedback current or voltage ? Also a Wilson current mirror is a shunt-series feedback ckt. But looking at a circuit like this I cannot easily find what is fedback. Moreover why is there a necesity of both current and voltage reference. we all know that V=IR. so if have a reference current and pass it to a resistor, can't we get a referenced voltage.
