模拟电子 校准ADC内部偏移的光学微控制器DS4830
Abstract: The DS4830 optical microcontroller's analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. Th ...
模拟电子 校准复用器简化系统校准设计
Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to ...
模拟电子 利用数字电位器调整并校准升压型DC-DC转换器
The purpose of this application note is to show an example of how a digital potentiometer can be used in thefeedback loop of a step-up DC-DC converter to provide calibration and/or adjustment of the output voltage.The example circuit uses a MAX5025 step-up DC-DC converter (capable of generating up ...
模拟电子 STM32F10xxx设备中如何得到高精度ADC
The STM32F10xxx microcontroller family embeds up to three advanced 12-bit ADCs (depending on the device) with a conversion time down to 1 μs. A self-calibration feature is provided to enhance ADC accuracy versus environmental condition changes.
电源技术 电源供应器与数字电位器校准应用笔记
Abstract: A resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solves the problem of adjusting a power supply. For easier automatic calibration, a mechanical pot can be replaced witha digital pot. This application note ...
传感与控制 如何选择补偿的硅压力传感器
Abstract: This reference design provides design ideas for a cost-effective, low-power liquid-level measurement dataacquisition system (DAS) using a compensated silicon pressure sensor and a high-precision delta-sigma ADC. Thisdocument discusses how to select the compensated silicon pressure sensor ...
无线通信 差分電路中單端及混合模式S-參數的使用
Single-Ended and Differential S-Parameters
Differential circuits have been important incommunication systems for many years. In the past,differential communication circuits operated at lowfrequencies, where they could be designed andanalyzed using lumped-element models andtechniques. With the freque ...
测试测量 产品检测中裕度和校准的乐趣
Abstract: This application note presents an overview of electronic margining and its value in detectingpotential system failures before a product ships from the factory. It is a calibration method that effectivelypredicts and allows adjustments to improve product quality. Margining also can be use ...

This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and ...
