hi
I have problem simulating a simple switch capacitor circuit in cadence virtuoso. when I put a big resistor as feedback it works but since it is switched capacitor it shouldnt have that resistor so when i remove it it has no dc convergence.
Does anyone have a simple realized schematic in...
Re: simple swtiched capacitor circuit using macro op apm mod
yes if you see my attached figure it has a very big output voltage:

Even when I use the separate power supplies (+1.2v & -1.2 v) it has the same problem. I understand what you mean and it doesn't really make sense to use DC analysis for the clocked circuits and I do the trans. analysis as well but yet in the DC analysis I...
simple capacitor circuits
thank you
1- but what should i do to make it works?
2- By the dc analysis I just want to check the output offset at the op-amp that should be reasonable at any time sample.
simple capacitor circuit
Hi
i am trying to simulate a very basic switched capacitor circuit in Virtuoso using a macro op apm model. But when i simulate, as you see in the picture
https://obrazki.elektroda.pl/70_1243607809.jpg
in DC analysis there is very big offset in the output.
and in...
The X1 is an OpampMacro from "functional" library but I can't find its proper model library (the .scs) file to add into my models. what should I do then?
I am trying to simulate a circuit in analog artist but I got some errors:
Error found by spectre during circuit read-in.
ERROR (SFE-23): "input.scs" 18: X1 is an instance of an undefined model f_oplv1c.
I don't know where I can find this library to add if the problem is to add the model library
cadence switched capacitor
Hi
I am trying to design a switched capacitor sampling system in virtuoso schematic editor. But I don't know how to:
1- Generate non-overlapping clocks.
2- How to model the switches? should I use like nfet or there are special switches?
Thank you,
M
offset of differential pair
Hi,
I am trying to simulate a simple differential pair amplifier but I see offset on my output how can I minimize this offset?
thanks,
M
Hi,
It is a very broad question and there are hundreds of thousands of different topics on which you can start your research but since you have a background on NGN I suggest you to start your research with studying different aspects and requirements on software defined radio (SDR) and next...
Dear friends,
As a part of my thesis which is to design a bandpass sampling receiver I have two basic questions to ask:
1- How to express and show a single sideband bandpass signal in MATLAB.
2- I have the transfer function of a complex FIR filter and the coefficients but I don't know how to...
