四个半桥A0,A1,A2,A3放置在正方形的四角，还有一个假桥A4作为补充，依次配对组成全桥，得到四组数据，然后用4个半桥的信号作为未知数可列四个方程，具有唯一解；当4个半桥的信号解出来之后，通过校正已知了每个半桥所对应的增益系数K，则将每个半桥数据*对应增益系数，然后求和就是总重量。

The op amp IC has become the universal analog IC because it can perform all analog tasks. OP AMPS FOR EVERYONE provides the theoretical tools and practical know-how to get the most from these versatile devices. This new edition substantially updates coverage for low-speed and high-speed applications, and provides step by step walkthroughs for design and selection of op amps and circuits. * Modular organization allows readers, based on their own background and level of experience, to start at any chapter * written by experts at Texas Instruments and based on real op amps and circuit designs from TI * NEW: large number of new cases for single supply op amp design techniques, including use of web-based design tool * NEW: complete design walk-through for low-speed precision op amp selection and circuit design * NEW: updates, including new techniques, for design for high-speed, low distortion applications. * NEW: extensive new material on filters and filter design, including high-speed filtering for video and data
