摘要

为了优化混频器的线性度，我们需要认识主要非线性的起源和混合机制。本文介绍了一种时变（TV）非线性分析，利用 TV 多项式模型在四个简单混频器结构中产生谐波混合函数。本地振荡器（LO）波形工程被用来定制非线性系数，然后将其输入数值失真贡献分析工具，利用基于 Volterra 系列的方法计算非线性。绘制了非线性电压的频谱，然后绘制了将最终 IM3 失真分解为其贡献的图谱。最后还说明了滤波对失真产生的影响。

A Study on Nonlinearity in Mixers Using a Time-Varying Volterra-Based Distortion Contribution Analysis Tool

To optimize the linearity of mixers, one needs to recognize the origins and mixing mechanisms of dominant nonlinearities. This article presents a time-varying (TV) nonlinear analysis, where TV polynomial models are used to yield harmonic mixing functions in four simple mixer structures. Local oscillator (LO) waveform engineering has been utilized to tailor the nonlinearity coefficients, which were later fed into a numerical distortion contribution analysis tool to calculate the nonlinearity using a Volterra series-based approach. The spectra of the nonlinear voltages have been drawn, followed by plots breaking the final IM3 distortion down into its contributions. The effect of filtering on distortion has been illustrated in the end.

期刊介绍： The IEEE Transactions on VLSI Systems is published as a monthly journal under the co-sponsorship of the IEEE Circuits and Systems Society, the IEEE Computer Society, and the IEEE Solid-State Circuits Society. Design and realization of microelectronic systems using VLSI/ULSI technologies require close collaboration among scientists and engineers in the fields of systems architecture, logic and circuit design, chips and wafer fabrication, packaging, testing and systems applications. Generation of specifications, design and verification must be performed at all abstraction levels, including the system, register-transfer, logic, circuit, transistor and process levels. To address this critical area through a common forum, the IEEE Transactions on VLSI Systems have been founded. The editorial board, consisting of international experts, invites original papers which emphasize and merit the novel systems integration aspects of microelectronic systems including interactions among systems design and partitioning, logic and memory design, digital and analog circuit design, layout synthesis, CAD tools, chips and wafer fabrication, testing and packaging, and systems level qualification. Thus, the coverage of these Transactions will focus on VLSI/ULSI microelectronic systems integration.
