Smart Noise - Linearity Breakdown in Homodyne Multi-Standard Radio Receivers
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 systematic noise - linearity partitioning methodology 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.
