Abstract

Dynamic Flash ADC has lot of applications in real time systems and mixed signal systems, where analog signals are converted to digital signals and then processed. In the present work, a new high performance dynamic Flash ADC is designed, which employs fast thermometer encoder and low power open loop comparator. Subsequently, a dynamic Flash ADC using standard cells such as NAND, NOR and INVERTER is also designed and implemented. Various parameters of the new dynamic Flash ADCs are analysed and it is found that these designs are best suited for low power applications. These dynamic Flash ADCs are designed in 180nm technology and post layout simulation is performed using Cadence Spectre tool.
