it was without R -44 dB and with R is -51 dBDon't worry. I guess we are not here for the rating. But yes, your helpful rating id there, I can see it.
What were the results of your THD simulations?
I am fedup of using CMOS filters, I think Gm-C filter is betterit was without R -44 dB and with R is -51 dB
These numbers doesn't look good. The most probably because of use mosfets as resistors.it was without R -44 dB and with R is -51 dB
What does it mean? Your cut off freq is lower or something else?then performance start to degrade, and some times too much
The cutoff frequency and the transfer function as well,What does it mean? Your cut off freq is lower or something else?
Thank you Dominik,Ok, so nothing special.
Annotate parasitic, add them to schematic and compare results.
If the same, then trim your poly caps to get proper results. Redraw, reextract, resimulate.
