ADC Limitations on the Dynamic Range of a Digital Receiver

摘要

With rapid developments of Microwave Monolithic Integrated Circuit (MMIC) and high-speed monolithic Analog to Digital Converter (ADC), digital receiver technology is widely used in modern radio systems. The performance of high speed ADC has a considerably impact on the performance of the digital receiver which uses direct IF sampling. The ADC error sources, such as, quantization noise, jitter noise and spurious component are introduced, and their effects on dynamic range of digital receiver are analyzed in this paper. The methods to improve the performance of the digital receiver are also discussed.
