Hi I did read the pdk kit. It was not described. I am not able to tell the difference between mc seciton and tt seciton. It seems that even if you refer to tt section and set devices to nch_mis, you still get mismatch simulations. The spread of results between pointing to tt section or mc...
Hi, I'm using 130nm TSMC monte carlo simulation. In their rf013.scs file, there is a mc section for monte carlo. There is also nch_mis/pch_mis for mismatch nmos/pmos transistors. I'm just wondering what the purpose is for the mc section if I am using nch_mis/pch_mis cells in my netlist. Thanks.

Hi LvW, I think I finally get you now.
When we derive the bandwidth of 1st-order RC filter, the "w" in the jwRC=j actually is w=2*pi*f where the 2*pi is JUST A FACTOR which is unitless. Therefore, w has the unit of 1/sec.
In order to extract the f in the w=2*pi*f, we need to divide 1/RC by...
Hi LvW, I digged deeper and I think I understand my issue better now, with your help, of course.
So the -3dB frequency for any 1st order RC filter is found by setting 1+j*w*RC=1+1j. This frequency is in rad/sec because wRC must have the unit of "rad" given that it is a phasor. Therefore, w=1/RC...
Based on your 2nd line, you are then saying that the number "1" in the numerator has the unit of "rad" (because we all know that RC at the bottom is in "sec"). If so, why? Could you please follow up? Thanks.
Hi, I have a question about time constant. For a 1st order RC filter, time constant=RC, which obviously has the unit of [second]. The bandwidth of this filter is 1/(2*pi*RC), which has the unit of [Hz]=[cycle/second]. I just don't know how this unit comes about. Here is my confusion:
If RC has...
