Analog/Digital Co-design Methodology to Achieve High Linearity and Low Power Dissipation in a Radio Frequency (RF) Receiver

Radio frequency (RF) receivers are fundamental in wireless communication, aiding in the translation of radio waves into audible or decipherable signals. As technology demands increase, there is growing need for RF receiver designs that consistently ensure high performance. Such performance, however, traditionally implies higher power consumption that may impact device battery life negatively. Current methods often struggle with upholding a balance between high-performance receiver operation and minimal power usage. Existing receiver designs frequently concentrate on analog receiver components or digital nonlinearity compensation separately. This disjointed treatment often results in less power efficiency and compromises receiver performance. So, there is an inherent need for a more integrative, efficient, and energy-conserving design.

Technology Description

This technology centers around developing radio frequency (RF) receiver design techniques. It approaches the design process holistically, considering in unison both the components of an analog receiver chain and digital nonlinearity mitigation methods. This unified consideration during design results in a highly efficient and linear RF receiver. A key advantage lies in power conservation, as the combined front-end technique leads to significantly reduced power usage in the receiver. What sets this technology apart is its hybrid approach, merging both analog and digital aspects during the design process. While individual components such as the analog receiver chain and digital nonlinearity compensation have their own energy benefits, the combined design brings about enhanced efficiency. This technology achieves linearitization without prejudicing power exertion, thus innovatively balancing the traditionally precarious trade-off between performance integrity and energy utilization.
