摘要

摘要: 射频集成电路(RFICs)对工艺偏差、器件失配、器件非线性等引入的静态非理想因素以及温度变化、增益改变、输入/输出频率变动等引入的动态非理想因素所表现出的鲁棒性较差。该文深入挖掘影响射频集成电路性能的关键因素，并对典型的校准算法进行归纳和总结，为高性能射频集成电路设计提供理论支撑。

Abstract: Radio Frequency Integrated Circuits (RFICs) show poor robustness to static non-ideal factors introduced by process deviations, device mismatches, device nonlinearities, and dynamic non-ideal factors introduced by temperature changes, gain changes, and input/output frequency changes. The key factors that affect the performance of RFICs are excavated deeply, and typical calibration algorithms are summarized to provide theoretical support for the design of high-performance RFICs.
