该论文提出了一种采用40nm CMOS工艺的宽带直接变频发射机,通过基于子采样的校准技术解决了输出功率、本振泄漏和I/Q不平衡问题,适用于MoCA等家庭网络宽带应用。
digital devices such as cameras, media players and high-definition TVs has seen a significant growth. This requires tuners for home networking such as MoCA with increasingly large bandwidth. Though advanced CMOS technology allows for the design of high-speed circuits and systems that can meet the need for more bandwidth, 40nm feature sizes and beyond introduce new challenges in analog circuit design [1]. Moreover, dependence on environmental conditions of device spread and matching performance with parasitic coupling can drastically reduce the overall system performance. The integration of analog/RF circuits with the digital part in an SoC enables the use of inexpensive DSP power to calibrate non-idealities. Digitally-assisted RF
