A 40MHz-to-1GHz Fully Integrated Multistandard Silicon Tuner in 80nm CMOS

📋 论文概要

该论文提出了一款在80nm CMOS工艺上实现的全集成多标准硅调谐器，覆盖40MHz至1GHz频率范围。通过采用软件无线电架构，该调谐器能够支持DVB-T、DVB-C、ATSC-A/74、DOCSIS以及模拟电视等多种标准，解决了全球市场对宽频带、多标准兼容性的需求。

💡 主要创新点

• 实现了40MHz至1GHz的宽频带全集成硅调谐器，支持多种电视和电缆调制解调器标准。
• 采用软件无线电架构，通过可编程的模拟前端和本地振荡器设计，在保持低噪声和高线性度的同时适应不同标准。

DVB-T, DVB-C, ATSC-A/74 as well as cable modems (DOCSIS) and analog TV require low-noise, high-linearity front-ends with high-performance local oscillators. Integrability and cost dictate minimization of external components. Unlike common approaches [1,2], the silicon tuner presented in this paper features one single-ended RF input for the entire 40MHzto-1GHz band, requires no external SAW filters or balun, and supports channel bandwidths from 5 to 8MHz. The analog IF output is programmable from 5MHz
