Hi All I am trying to simulate a chopper stabilized amplifier circuit using multisim or LTspice.
Does anyone have any resource(i.e. schematic files or detail schematics) related to implementing chopper stabilized amplifier using Multisim or LTspice. Could you please send me a copy?
I really appreciate your help
Thanks in advance
I have not noticed any chopper modulator type device or component part in LTSpice, then again I'm not a regular user of the software. However, you can design your chopper modulator using MOSFETs as switches. See the paper: "A CMOS Low-Noise Instrumentation Amplifier Using Chopper Modulation" by Nielsen and Bruun.
The LTC1043 is in there.
You can also make a fairly simple model of a relay.

Hi I searched the component name LTC1043 on LTspice, but I can't seem to find it. Is it an extra component I need to download?
If you have one, can you please email me a copy?
I simulate my chopper stabilized circuit on multisim because I can't find a way to generate spectral analysis of a signal on LTspice. Can LTspice do spectral analysis?
A major problem I have right now is I can't get the opamp stage of my chopper stabilized amplifier to work. I try to simulate Fig4a in the article "A CMOS Chopper Amplifier" by Christian C. ENZ.
I can get the input modulator to work but after I attach the opamp, I get a "timestep too small" error message every time I simulate. I tried changing the end time to a big number, but it doesn't fix the problem either :(
Can someone please give me some assistant.
I can email you the article and my multisim file if that makes it easier to understand my problem
Thanks
