Two-Stage Amplifier and Spectre Simulation - ECE x321 EDA Tutorial 2
Вставка
- Опубліковано 8 жов 2024
- In this video, we will design a two-stage differential amplifier schematic and symbol, then design a test bench to simulate the design. We will discuss DC simulations, as well as AC, stability, and transfer function simulations to find the loop gain, closed-loop gain, and closed-loop output resistance for a unity-gain buffer.

Thank You so much for such a nice tutorial. I completed this video in 6 hours by implementing the design and learning Virtuoso both simultaneously. Thanks again
bro u literally saved my life...!!! A very good explanation and thanks a lot
Thank you for doing this video. This is easily the best explanation for this simulation setup on the internet :)
Thank you for your kind words! :)
Thanks, Man!!! A fantastic presentation 👍
My pleasure!
Very Helpful.. thank you so much..
Hi. Could you please tell me how to install Virtuoso the way you have - on Windows (judging by the fact that the software uses the Windows interface)? Or are you using a virtual machine?
Sometimes it is not always convenient to use the Linux version. Thanks!
Thank you for your video .Why power gnd connected through inductor .Is it avoid noise coupling? or else any other reason bro.Could you please revert us?
The power and GND connections are connected through an inductor to simulate the inductance of the bond-wires used to bond the chip to a package. For lower frequencies this may not have a major issue, but at higher frequencies the inductance can have a more profound impact on the operation of the circuit and should be considered.
Thank you for this video. One query is : Should the ibias terminal in testbench be connected to Vdd and not ground?
It shouldn't matter since you are still imposing a constant current draw (i.e., the source will draw the same current whether you have the other side connected to VDD or ground). The primary purpose of Ibias is to measure the small-signal impact of injecting a current, which translates to the output impedance using the transimpedance xf analysis.
Can you tell my what kind of simulator that you use on cadence
Is it spectre or what ??
Thats is a interview Q??
Yes, this is Cadence Spectre, with the NCSU analog PDK.
@@aaroncarman thank you
hi, do you have a tutorial for ldo using this op amp?
Unfortunately I don’t have any LDO tutorials at the moment. You may be able to find good information in LDO chip application notes!
hello！ can you share your PDF for me？ please！
what is the tech node for this?
Hi, can you share the document ?!
Ablsoutelt Terrible. How can you Be so helpful? Its just selfish for you to be so nice to those of us who are so damn grateful. 0/10
This is soooooo long... Be a little faster.. thanks..
