Hi,
I’m currently studying some designs and my tutor asked me this question : « should switches be put before or after resistors ? ».
I do have an idea that it has to do with MOS parasitic caps (my case uses a NMOS/PMOS switch) but I don’t know where to start to prove it.

I’m not necessarily looking to have the solution totally given to me but if I could have some help to start on how to prove which one is better (for gain, BW, phase margin, noise …), I’d be very happy.

Thanks !
