What are the advantage of reduced length devices in signal path. example.. a simple differential receiver or a signal comparator.. the size of the receiveing differential pair MOS length is minimised and the width is maximised.. is there any paritcular reason for this.. thanks.

Up to some point, front end gain is the most significant thing you can play with for low- overdrive differential amplifier speed.
