Newbie level 6
I have read this document : https://www.designers-guide.org/Analysis/sc-filters.pdf
I want to re-simulate the example named Track & hold .
This problem confuse me :
If the previous MOS model ( Level-3 model ) is used, the PAC & PXF result is similiar whith that in the paper. but if the my BSIM3V3 models is used, the result is absolutely different or wrong, the voltage gain is almost zero except DC frequency.
I use MMSIM6.1 version and IC5141 Base.
Anything is wrong ?
I use +-2.5V VDD & VSS voltage. My technology can accept 6V voltage.
Need helps!!
