Abstract:
This paper analyzes the noise–linearity breakdown in direct conversion multi-standard radio receivers embedding analog signal conditioning. The paper’s main goal is to develop a sys-tematic noise–linearity partitioning methodol¬ogy to be used in splitting the multi-standard receiver noise and linearity budget between its high frequency (HF) part and its low frequency (LF) baseband part. To this aim, a new and efficient design methodology tailored towards multi-standard receivers, and based on manual analysis, is developed. By using the developed methodology, power saving is enabled in the HF part through changing the multi-standard receiver HF part noise and linearity performance with its RF front-end gain. While for the LF part, the analysis revealed the performance can be kept the same to allow power optimization through dedicated circuit design.
