Internet of Things (IoT) applications depend on smart objects that interact with the real world. These objects can contain Micro Electro-Mechanical Systems (MEMS) – based sensors that convert physical or chemical actions into data that is collected for analysis. A key building block for sensor design is the resonator. Resonators are crucial for devices that include: timing references, mass recording, motion sensing, biological sensing, signal filtering, and energy harvesting. This paper shows how to engage Tanner EDA tools to create an example resonator device.
