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。

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 ...

Developing embedded software is an increasingly complex problem. As the world moves to multi-core, multi-architecture devices, software engineers need to leverage and debug different processing ...

Comparator ICs are designed to compare the voltages that appear at their inputs and to output a voltage representing the sign of the net difference between them. In a comparator circuit, if the ...

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 ...

The thermocouple is a simple, widely used component for measuring temperature. This article provides a basic overview of thermocouples, describes common challenges encountered when designing with them ...

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 ...

Even with the widespread use of rail-to-rail single supply op amps, there is still often the requirement for dual rails (for example, ±15 V) to be generated from a single (positive) input power rail ...

An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails (that is, analog and digital rails for mixed-signal ICs) while preserving high ...

The EE-Sim DC-to-DC converter tool uses your requirements to quickly create a complete power design including a schematic, BOM with commercially available parts, and time and frequency domain ...

Low-dropout regulators (LDOs) are deceptively simple devices that provide critical functions such as isolating a load from a dirty source or creating a low-noise source to power sensitive circuitry.
