Thank you very much frankrose. Thanks to you, I have been able to understand most of these things. Most of the books just give definition of large signal analysis and then just move on to small signal analysis. I have been confused about dc models and large signal models for so long. To just...
About my 2nd point: So all dc models are large signal models but not vice versa?
About my 6th point: I needed something to distinguish between DC models and Large Signal Models, as some books just claim them to be same. But I kind of knew they are different. So I said that when we consider...
Hi frankrose,
Thanks for your reply.
Based on the knowledge gained, I have made some pointers. Please verify if these are correct or not:
Large signal models do both ac and dc analysis.
Large signal models are also called dc models or large signal dc models.
Small signal models do only ac...
I am studying microelectronics. I have studied about the DC analysis and the AC analysis. The DC analysis is just to find the operating point or the quiescent point and then the AC analysis is done. An AC analysis can be done in two ways for non-linear devices (like diodes and transistors)...
I am studying microelectronics. I recently got confused about about the small signal models and large signal models. After reading an extensive list of sources, I have come up with some pointers which I want to verify that I have got right.
The term "small signal" can refer two things : small...
But the common mode signal parameters are indeed included in the closed loop configuration of op-amp circuit. Refer to think link: Sedra Smith
What I don't understand is why common mode signal parameters of op-amp not included like I have shown in the last equation in above post (unlike it...
Consider an open loop opamp circuit:
Now consider the second circuit in a closed-loop configuration (negative feedback):
Why are internal common mode signal parameters not included in the internal gain equation of the op-amp? Is my interpretation of all these concepts correct?
References...
For an opamp in open look configuration,
Here Ad should be equal to open loop gain of opamp and
Now consider the closed loop config of opamp (negative feedback used):
Again,
However, Ad is closed loop gain here (according to Sedra Smith) and
In terms of open loop gain,
A is open loop...
