Designing Successive Approximation Register ADC by Using Double Tail Comparator
Neha Sharma, Rachna Manchanda
Abstract: In high speed communication systems, data converters are most important for a transmission. Successive Approximation Register ADC is used as a sub-ADC of time interleaved ADC because its simplicity, linearity, low power consumption, and low latency. In this paper the double tail comparator is designed using Tanner 13.0 software and the power consumed is 1.467 Watt. Then it is implemented in the slowest Successive Approximation register and the power consumption is analyzed. It is noted that the power and speed is increased due to implementation of double tail comparator. Power consumption is reduced to great extent. In this paper, SAR ADC is designed in 0.65um CMOS technology with power supply of 0.705v for vinn and supply voltage for vinp is 0.710v. This design is working on 500MHz frequency. Delay, average power, maximum peak power is analyzed.
