Abstract |
This paper proposes a 4-bit, 1.8V, Flash ADC (Analog to Digital Converter) design using CMOS Comparator with 180nm technology. The conventional comparators have been replaced with the CMOS inverter based comparator designs. The PSRR (Power Supply Rejection Ratio) results obtained are improved with the use of CMOS comparator and by systematically sizing the transistors of the comparators. Thus it has been observed that it consumes 0.46827mW of average power. |
