低压差稳压器(LDO)看似简单，但可提供重要功能，例如将负载与不干净的电源隔离开来或者构建低噪声电源来为敏感电路供电。 本简短教程介绍了一些常用的LDO 相关术语，以及一些基本概念，如压差、裕量电压、静态电流、接地电流、关断电流、效率、直流输入 ...

电路中的噪声通常都是有害的，任何好电路都应该输出尽可能低的噪声。尽管如此，在某些情况下，一个特性明确且没有其他信号的噪声源就是所需的输出。 电路特性测量就是这种情况。许多电路的输出特性可通过扫描一定频率范围内的输入信号并观测设计的 ...

很多应用都需要差分信号，包括驱动现代模数转换器(ADC)、通过双绞线电缆传输信号、调理高保真音频信号。由于差分信号在一组特定电源电压下使用较大信号，提高了对共模噪声的抑制能力，降低了二次谐波失真，因而实现了更高的信噪比。由于这一需求 ...

Op amps are very high gain amplifiers with differential inputs and single-ended outputs. They are often used in high precision analog circuits, so it is important to measure their performance ...

Many industries are calling for electronics that can operate reliably in harsh environments, including extremely high temperatures. Traditionally, engineers had to rely on active or passive cooling ...

This application note presents the electrical aspect of the 1-Wire protocol for new and legacy devices. A special section explains how to determine appropriate timing parameters for a network ...

Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others. This article ...

Today’s designs require an increasing number of power rails and supply solutions in electronics systems, with loads ranging from a few mA for standby supplies to over 100A for ASIC voltage regulators.

The phenomenon of current noise increasing with frequency is well known to IC design engineers and circuit designers, but it was elusive to many engineers as a result of either too few articles in the ...

One common method for determining the tilt or inclination of a system is to integrate the output of a gyroscope. Although this method is straightforward, error ...
