传感器的信号调解
传感元件（传感器）将有用的物理信号转换为电信号，例如：用于测量压力的压阻桥、用于检测超声波的压电传感器以及用于测量气体浓度的电化单元等。传感元件产生的电信号都很小，并且为非理想状态，例如：温度漂移和非线性传输函数等。
传感器模拟前端和传感器信号调节器，用于把这些传感元件所产生的小信号放大到可用水平。传感器包含完整的信号调节电路，以及可刺激传感元件、管理功率并与外部控制器连接的一些电路。
为了实现信号调节或更高层次的监测，通常需要测量多个传感器元件的输出。举例来说，处理一个典型压阻桥的输出，就需要同时测量压阻桥和温度传感器的输出。此外，热电偶的输出处理，要求同时测量热电偶的输出和传感器的输出，测量接头的温度。对接头温度的测量是为了完成冷接头补偿。同一信号调整器处理多个感测元件的情形称为“多模态信号调整器”。
传感器信号调节的另一个方面是发生信号调节的电域。传感器的电阻桥传感元件的信号调节发生在模拟域内。在传感器中，信号调节同时发生在模拟和数字域内。后一种情况被称作“混合信号信号调节”。
混合信号调节器的一个关键组成部分是模数转换器（ADC）。在信号达到智能补偿模块以前，两个传感元件始终都有立的信号通路。之后，该模块组合这两个信号，产生经过处理之后的输出。
