| Abstract: | A new, fully differential comparator with rail to rail input range is presented. This comparator can be used as a 1-bit quantiser in sub-1 V /spl Delta//spl Sigma/ modulators. The quantiser is laid out in 0.18 /spl mu/m CMOS technology. The post-layout simulation results show that the quantiser is capable of working at 10 MHz with 10 /spl mu/V resolution. This quantiser is successfully used in 0.8 V first-order and second-order fully differential /spl Delta//spl Sigma/ modulators. |
