AN INPUT SIGNAL STATISTICS AWARE DESIGN APPROACH AND EXAMPLES FOR ANALOG-TO-DIGITAL CONVERTERS FOR COMMUNICATION SYSTEMS

Abstract

Most of the analog-to-digital converters (ADCs) nowadays are designed for a specific application and embedded in a System-on-Chip (SoC) instead of a stand alone ADC chip for general purpose. In this case, the ADC input signal statistics is known information, while in different systems it can be far different from others. This observation gives opportunities to design ADCs smartly in a system context to achieve the required system performance at minimal complexity, area and power. In this paper, an input signal statistics aware design approach for ADCs for communication systems is discussed and two parallel ADCs architectures based on this approach are proposed for converting multi-carrier signal.
