My question is about regenerative latched comparators.
I'm not sure if I posted this question in the correct forum, but since I know that these circuit topologies are frequently used inside modern A/D converters, I thought there might be some experts here who can shine a light on this.
My question is not related to a specific part number but I was wondering why regenerative latched comparators are not offered as discrete parts by any manufacturer.
As much as they are indispensable in modern ADC architectures , they would make for a killer component in many mixed signal applications where high speed analog comparing and low power are key requirements. The speed to power ratio could be vastly improved for any time-discrete design, where there is now no other alternative than to use a power hungry linear comparator. Such a component would be a perfect supplement to modern ultra low power logic families and with only 6 pins needed could be housed in similarly small packages.
Is there a technical reason why such components don't exist or is there just no market for them?
