  • Analog to Digital Converter (ADC) is a necessary component of mixed signal designs. It converts the analog signal to the digital signal so that it is used as a bridge. This paper proposes R-Flash ADC (Reliable Flash ADC) which combines an area efficient multiplexer pass gate (MPG) encoding technique and low power ITIQ (Improved Threshold Inverter Quantization) comparator. The proposed Flash ADC is implemented using tanner EDA with 125 nm technology. R-Flash ADC reduces the number of transistors by 39% and reduces the power consumption by 59% with high resolution quality when compared to Mux TIQ ADC. The reliability analysis shows that the proposed R-Flash ADC has reliability of 95% and it overcomes the existing techniques as well.
