Amid the swift evolution of artificial intelligence technology, particularly embodied intelligence, the necessity for sensing and interactive capabilities in the physical world has surged. Serving as a vital link between the physical and information realms, the significance of the sensor readout front-end has grown increasingly prominent. This front-end converts physical quantities, such as vibration and magnetic force, into delicate electrical signals and performs high-precision digital processing for utilization by AI systems. For embodied intelligent agents, precise sensor data forms the cornerstone upon which AI models comprehend their environment, offering physical perception support for interactions and intelligent behaviors in complex scenarios. Likewise, invasive brain-computer interface systems hinge on high-precision sensing technology to enable brain interaction. The advancement of these technologies will further propel the application of artificial intelligence into a broader spectrum of fields.
