Low-Power Rail-to-Rail Comparator in 130 nm CMOS Technology

The paper addresses a novel comparator topology capable of processing the input signal in rail-to-rail range, designed in standard general purpose twin-well nanoscale CMOS technology without two differential input pairs. The power supply voltage of 1.2 V was used and the operating temperature span was set to a standard industrial limits (from −20 °C up to 85 °C). Its application is aimed to low-po...
