Hi Attila, everyone, very interesting discussion! >People talk of aliasing and sampling, but do not describe where the sampling happens in the first place. After all, it's a time-continuous system and as such, there is no sampling.
I would say that the sampling occurs when you're using only a slice of an input signal. For instance, If you're using only the zero-crossing slice of a sinewave to produce a divided version rather than the full envelope. It's a matter of how you process information in your circuit. >"A Physical Sine-to-Square Converter Noise Model," > by Kinali, 2018 I read the paper, very interesting as well! I have a minor remark, in the paper you relate the ISF (let's say "sampling window") to the output slew rate of the comparator. I would say that the sampling window should be related to the comparator input stage bandwidth. If you have an high bandwidth input stage (e.g. 5 GHz) followed by a slew rate limited output stage (e.g. 100 MHz) , high frequency noise will trigger the output circuit and aliasing it. Viceversa, if you have a low bandwidth input stage, even if the output stage is very fast, you don't get input noise aliasing. cheers Mattia Il giorno lun 17 set 2018 alle ore 13:46 Attila Kinali <att...@kinali.ch> ha scritto: > On Sun, 16 Sep 2018 23:06:06 +0200 > Attila Kinali <att...@kinali.ch> wrote: > > > [2] "A Physical Sine-to-Square Converter Noise Model," > > by Kinali, 2018 > > Oops..
