PCB相关 华为的电路板设计规范
PCB（Print circuit Board)：印刷电路板。
1..2 原理图：电路原理图，用原理图设计工具绘制的、表达硬件电路中各种器件之间的连接关系的图。
模拟电子 正确的混合信号设计印刷电路板(PCB)的接地
Abstract: This tutorial discusses proper printed-circuit board (PCB) grounding for mixed-signal designs. Formost applications a simple method without cuts in the ground plane allows for successful PCB layouts withthis kind of IC. We begin this document with the basics: where the current flows. Lat ...
模拟电子 双绞线和低通滤波器降低EMI_RFI
Abstract: Alexander Graham Bell patented twisted pair wires in 1881. We still use them today because they work so well. In addition we have the advantage ofincredible computer power within our world. Circuit simulators and filter design programs are available for little or no cost. We combine the ...
模拟电子 高精度I2C实时时钟的设计
Abstract: This application note presents an overview of the operational characteristics of accurate I²C real-time clocks (RTCs),including the DS3231, DS3231M, and DS3232. It focuses on general application guidelines that facilitate use of device resources forpower management, I²C communi ...
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 XAPP854-数字锁相环(DPLL)参考设计
Many applications require a clock signal to be synchronous, phase-locked, or derived fromanother signal, such as a data signal or another clock. This type of clock circuit is important in
模拟电子 Stabilize Your Transimpedance Amplifier
 
Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltagesignals, since several circuits and instruments can only accept voltage input. An operational amplifier with a feedback resistor fromoutput to the inverting inpu ...
模拟电子 数字集成电路设计Digital Integrated Circuit Design
 
This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Coverin ...
模拟电子 你的PLD是亚稳态吗
This application note provides a detailed description of themetastable behavior in PLDs from both circuit and statisticalviewpoints. Additionally, the information on the metastablecharacteristics of Cypress PLDs presented here can help youachieve any desired degree of reliability.
