Problems solved by technology

[0005] At present, in the application of sensors, most of the circuits are separated from the sensor and its signal processing circuit. The biggest problems in this way are large size, high cost, and difficult packaging, especially in the design of signal circuits for automotive-grade pressure sensors, The compensation method of temperature characteristics and the automation level of the production process are very low, which affects the stability of the sensor, and at the same time cannot achieve mass production, so the sensor needs further improvement
