For my project, I am planning to use the ADCMP572 comparator. I want to generate a hysteresis of ~50mV for my incoming signal, which has a BW of ~2.5GHz. So, I was looking for the LTSpice model of the device but couldn't find any. How can I proceed with the simulation from here on?
I think we have a model for ADCMP573. I'll try to search for it internally and attach it on my next response.
Did you get a chance to find the model? I apologize for the rush. Thank you for your time!
Unfortunately we don't have the officially released ADCMP573 spice model. I have here a very raw model which you could probably use just for functionality check. Please check the attached cir file. adcmp573_new.zip
Can you share on what type of application ckt you are using the ADCMP573?
Hi Debadri and Arthur,
I have this question: is it even correct to use spice modeling of ultra-fast comparators? After all, the slightest capacitance and inductance on the board will have a significant impact and accounting for all this is a very difficult and painstaking work. Or am I wrong?
