摘要：In this paper, 5-bit flash analog-to-digital converter (ADC) for low voltage and high speed ultra wideband (UWB) applications is presented. To achieve high speed threshold inverter quantization (TIQ) technique is utilized in comparators design. The thermometer to binary decoder can be designed using fat tree decoder, wallace tree decoder, ROM decoder, multiplexer-based decoder etc. We implemented multiplexer-based decoder which has advantages of having regular structure and shorter critical path over existing decoder circuits. The 5-bit flash ADC has been designed and simulated in 0.18?m CMOS technology using tanner design tools and achieved INL, DNL values less than 1LSB and effective number of bits of 4.29-bits.
