Local programmable automatic compensation technology of silicon piezoresistive pressure sensor

为了提高硅压阻式压力传感器温度性能指标，并实现快速补偿，通过以ADμC816微处理器为核心设计了智能压力传感器，提出了传感器在宽温区下测量误差的自动补偿办法，通过对IC sensor系列压力传感器的应用，使其温度性能提高了1-2个数量级。

In order to improve the temperature performance of the silicon piezoresistive pressure sensor and achieve rapid compensation, a smart pressure sensor based on ADμC816 microprocessor is designed, and a automatic compensation mean is introduced for the measurement error under wide temperature range. The result presents that the temperature performance of the IC sensor series of pressure sensor is improved 1 - 2 order of magnitude by this way.
