Redundant analog to digital conversion architectures in CMOS technology

The operation of modern electronic devices in different fields as communications, signal processing, and sensor interface is critically affected with robust, high performance and scalable Analog-to-Digital Converter (ADCs), that can be considered as one of the main blocks in many systems, since they are mandatory to make the link between the analog outside world and the evermore-ubiquitous digital computer world. The design of these ADCs come distinct tradeoffs between speed, power, resolution, and die area embodied within many data conversion architectural variations. The flash ADC structure are often the base structure for high-speed operation and simple architecture analog-to-digital converters (ADCs). As the input signal is applied to (2
