In this paper, the authors concern the design of Flash type of Analog to Digital Converter (ADC) which is more likely to be used for high quality audio and video signals. It uses resistor ladder logic, comparator and encoder to convert the continuous input signal into binary form. Comparator, encoder circuits are designed using CMOS technology and its output response is obtained to meet the requirements. Comparators form the main element to design flash ADC. Different architectures of comparators are designed to build 4 bit flash ADC. Dynamic characteristics of the converter are analyzed and its performance is compared with different comparator architecture.
