Fast static CMOS comparator circuit

Hi all,

Could you recommend some key/good papers about static CMOS comparators (not dynamic ones)?

Thank you very much.

Static CMOS comparators are not really good when it
comes to Vio (t=0, and drift). That's why so many are
clocked (that, and low quiescent power).

If you were clever and had the die area and a handy
clock resource, you could make a ping-pong comparator
that zeroed one side while the other was real-time
("static").

High gain is the enemy of high bandwidth. Low power
is the enemy of high bandwidth. High common mode
range, yadda yadda. What are you willing to sacrifice,
what technology can you stand to use given the other
requirements? It's not like you're going to get a 12nm
FinFET comparator to handle +/-10V input common
mode range, and it's not like you want to use a 40V
bipolar process to be a high speed serial receiver
front end when its swing is a hundred mV and its
common mode is pinned to 0.5V +/- 50mV either.
