A new robust over rail to rail comparator based on DCG-FGT transistor

A new comparator based on Dual Control Gate Floating Gate Transistor (DCG-FGT) that allow increasing input voltage range over rail-to-rail is proposed. The comparator operates with a supply voltage ranging from 1.6V to 3.6 V in 90 nm CMOS technology. The comparator is simulated under ELDO and consumes 3.2μA under typical condition.
