A Digital Synthesizable Full Common-mode Input Range Dynamic Voltage Comparator

This paper presents a digital synthesizable full common-mode input range dynamic voltage comparator (FCMRDVC). It is a modified version of the rail-to-rail dynamic voltage comparator (RRDVC), with a view to a real rail-to-rail common-mode input range (CMR). The proposed FCMRDVC is designed and synthesized in 28-nm CMOS technology with the active area of 43.2µm
