Hi, all

I am trying to build an anolog comparator in 0.35um process.  I suppose that this comparator can operate at high frequency, for example, a 100MHz triangle wave form and 30MHz sinusoid signal at the input. But the result seems that the comparator in 0.35um process is not that sensitive at this frequency, can anybody have done this before ? Please give some suggestions about how to build this comparator? Thank you very much.

Hi, carlgrace,

I think the cross coupled latch circuit they all need a clock signal, which is not the case in my circuit.

I checked the Razavi book, which chapter do you mean 'data converters'?


Thank you very much.
