摘要

本文分析了低温共烧陶瓷(LTCC)多层结构中嵌入电阻的频域和时域响应，并讨论了它们对混合信号电路高频工作的影响。结果已经比较了TDR(时域反射)和TDT(时域传输)测量使用脉冲传播。从测量和模拟中观察到，频率依赖性寄生在嵌入式电阻器中是显著的。本文强调了准确建模的重要性，包括频率依赖性和寄生性，以预测嵌入式电阻的频率行为。建立了电阻器结构的宏观模型，仿真结果与实测结果吻合较好。本文还讨论了一种提供与测量良好相关性的宏观建模方法。

Characterization of embedded resistors for high frequency wireless applications

This paper analyzes frequency and time domain response of embedded resistors in a multilayered structure using LTCC (low temperature co-fired ceramic) technology and discusses their effect on high frequency operation of mixed signal circuits using them. The results have been compared to TDR (time domain reflectometry) and TDT (time domain transmission) measurements using pulse propagation. Frequency-dependent parasitics are observed to be significant in embedded resistors from measurements and simulations. The importance of accurate modeling including frequency dependence and parasitics is emphasized in this paper for prediction of the frequency behavior of embedded resistors. Macromodels for resistor structures were developed and their simulation results show a good agreement with measurements. This paper also discusses a macromodeling approach that provides good correlation with measurements.
