Summary |
In this chip, we integrate sensor read-out circuits for Piezo wave sensors and Bio-potential sensor. We’ll use these two circuits combines with an external Piezo material to create temperature, viberation, pressure and ExG sensors. The sensor data can later be analyzed and processed by the embedded ARM-like processor in realtime within the SoC and store in a circular buffer using reverse encoding technique which has high utilization and small overhead. The processed and compressed data has higher abstraction level than raw data that save bandwidth while transmitting data. The embedded processor can also improve the precision of the sensor by on-line calibrating and better de-noise algorithm. |
