本研究提出一种用于频域模拟矢量矩阵乘法的频率同步电路模型，该频率同步通过全连接耦合振荡器实现，每个振荡器采用互补交叉耦合跨导对和RC高通滤波器构建。研究不仅单独使用振荡器实现频率同步，还探讨了振荡器与谐振器模型（即MEMS/NEMS谐振器）结合的配置方式；在解决所有耦合振荡器的频率同步问题的同时，还讨论了通过控制选定振荡器子集的耦合强度实现的部分同步。该频率同步分析采用模拟电路和谐振器模型进行小信号分析，从而可理解由模拟电路和谐振器模型参数定义的同步频率。
英文摘要
This work introduces a frequency synchronization circuit model for analog vector-matrix multiplication in the frequency domain. The frequency synchronization is implemented by coupling oscillators through all-to-all connections. Each oscillator is implemented using complementary cross-coupled transconductance pairs and RC high-pass filters. In this work, the frequency synchronization is achieved not only using oscillators alone but also through a configuration in which oscillators and resonator models (i.e., MEMS/NEMS resonators) are combined. While addressing the frequency synchronization of all the coupled oscillators, a partial synchronization is also discussed by controlling the coupling strength of a selected subset of oscillators. This frequency synchronization analysis focuses on the small-signal analysis using analog circuit and resonator models, thereby enabling an understanding of the synchronized frequency defined by the parameters of the analog circuit and resonator models.
