Flexible Discrete Passive Filter with Minor Strain Suffering

This paper proposes a flexible passive filter and summarizes the design rules of a flexible filter from the perspective of physical design methods. Compared with the filter design method of lumped structure, the distributed structure can reduce the effect of stress and transfer the stress of flexible deformation from the device itself to the substrate, and under a certain range of stress, the device can maintain good performance. In this paper, the above viewpoints are well verified by simulation experiments. A distributed structure is used to design the passive filter, which reduces the stress damage and stress induced performance impact of the device, and provides theoretical guidance for enhancing the reliability design of the flexible filter.
