Abstract:
Of all types of ADCs the flash ADC is not only famous for its data conversion rate but also it becomes the part of other types of ADC for example pipeline and multi bit Sigma Delta ADCs. The main problem with a flash ADC is its power consumption, which increases in number of bits. This thesis presents the comparison of power consumption of different blocks in 1Gbps flash ADCs for 2, 4 and 6 bits in a 90nm CMOS technology. We also investigate the impact on power consumption by changing the design of decoder block.
