Abstract
Analog-to-digital(A/D) converters provide the connection between analog and digital signals.
The architectures of A/D converters can be commonly defined as single-step and multistep.
In this thesis the flash topology of the first class is studied in detail.
A development review looks into the basics, theory and applications of ADC technology today.
To improve the performance of a flash ADC, the efficient solutions for different design consideration are also studied.
An ADC design is presented following the technology review.
Each component of a comparator, e.g. preamplifier, dynamic latch, and output stage is designed based on the practical consideration.
The interpolation technology is utilized to integrate the designed ADC.
Different performance test and simulation results give a conclusion for the ADC design.
