Analysis and Design of a 2.5GS/s 6-bit SAR ADC with a 3-bit/cycle Resolving Scheme

The thesis analyzes the design challenges that arise when developing high-speed ADCs and shows, through an extensive architecture study, that the SAR topology can be used with a sampling rate of 2.5GS/s if asynchronous processing and a multi-bit per cycle approach are adopted. The transistor-level implementation and simulation of a 6-bit SAR ADC...

Bit-error rate measurement setup and comparator design

Bit-error rate (BER) of comparators is becoming one of the limiting factors in the design of high speed ADCs. BER measurement setup is introduced and implemented in this thesis. Using this BER measurement setup gives us the opportunity to compare the BER of different comparators. It also enables us to study the effect of different parameters...
