摘要
本文介绍了工艺故障(如参数变化和工艺变化)对混频器特定参数的影响，如线性度(1 dB CP, IIP3)，噪声系数，电压转换增益，电压输出信号。对显示混合器规格和参数之间关系的数学类型的回顾是解释在过程移位和寄生元件存在下电路行为的工具。采用90nm CMOS UMC技术设计了一个带退化电阻的差分吉尔伯特单元有源混频器，以验证理论结论，并研究在改变一个或多个参数的情况下将电路处方恢复到期望值的可能性。
The Impact of Process Faults on Specific Parameters of a 1.9GHz CMOS Mixer
This paper presents the impact of process faults - such as parameter variations and process variations - on specific parameters of a mixer - like linearity (1 dB CP, IIP3), noise figure, voltage conversion gain, voltage output signal. A review of mathematical types that shows the relations between specifications and parameters of the mixer is the tool to explain the behavior of the circuit under the presence of process shifts and parasitic elements. A differential Gilbert-Cell active mixer with degeneration resistors has been designed in a 90nm CMOS UMC technology to validate the theoretical conclusions and investigate the possibility of restoring the circuit prescriptions to the desired values, varying one or more parameters.
