课程名称: VSD 实习生 - 使用 Sky130 PDK 进行 DAC IP 设计 - 第三部分 课程概述: 本次网络研讨会的目的是从零开始进行 10 位电位器数字到模拟转换器 (DAC) 的模拟布局设计，使用 Magic 和 Sky130 PDK。目标是布局并生成一款工作在 3.3V 模拟电压、1.8V 数字电压和 1 个外部电压参考的 10 位电位器 DAC。这是 Harshitha Basavaraju 主讲的 "VSD 实习生 - 使用 Sky130 PDK 进行 DAC IP 设计 - 第二部分" 的后续研讨会。 在现实世界中，大部分数据以模拟形式存在。我们有两种类型的转换器：模拟到数字转换器 (ADC) 和数字到模拟转换器 (DAC)。这两种转换接口对实现数字电子设备与模拟电气设备的数据操作至关重要。数字到模拟转换器 (DAC) 是将数字数据转换为模拟信号的设备，以便与现实世界进行交互。数字信号用二进制代码表示，即由 0 和 1 组成的位组合。数字数据可以来自微处理器、现场可编程门阵列 (FPGA) 或专用集成电路 (ASIC)。 DAC 的两种常用转换方式包括加权电阻法和 R-2R 梯形网络法。DAC 的应用包括音频放大器、视频编码器、显示电子、数据采集系统、校准和数字电位器。 本次网络研讨会将覆盖内容包括： - DAC 基础知识的介绍 - DAC IP 规格介绍 - DAC IP 设计基础和工具安装 - DAC 电路拓扑结构 - CMOS 剖面 - 金属层 - 电阻和电容布局理论 - Magic 工具基础 - 电阻和电容布局演示 - 反相器和开关布局的现场实验 - 10 位 DAC 布局设计和后布局分析 - DNL 和 INL 理论及计算 本课程适合有志于深入理解数字到模拟转换器设计的学习者。
The webinar aims to do analog layout design of a 10-bit potentiometric Digital to Analog Converter, from scratch, using Magic and Sky130 PDKs. The target is to layout and generate GDS for 10-bit potentiometric DAC with 3.3v analog voltage, 1.8v digital voltage and 1 off-chip external voltage reference. This is a follow-up webinar of "VSD Intern - DAC IP design using Sky130 PDKs - Part 2" conducted by Harshitha BasavarajuIn real world, most of the data available is in the form of analog in nature. We have two types of converters analog to digital converter and digital to analog converter. These two converting interfaces are essential to obtain the required operations of a processor to manipulate the data of digital electronic equipment and an analog electric equipment. Digital to Analog Converter (DAC) is a device that transforms digital data into an analog signal in order to interact with the real world. The digital signal is represented with a binary code, which is a combination of bits 0's and 1's. The digital data can be produced from a microprocessor, Field Programmable Gate Array (FPGA), or Application Specified Integrated Circuit (ASIC). There are two commonly used DAC conversions - Weighed resistors method and R-2R ladder network method. Applications of a DAC: audio amplifier, video encoder, display electronics, data acquisition systems, calibration, Digital potentiometer.This webinar will cover:IntroductionIntroduction to DAC fundamentalsIntroduction to DAC IP SpecificationsDAC IP design basics and tool installationTool InstallationsDAC Circuit TopologyBasics of DAC IP LayoutCMOS Cross Sectional ViewMetal LayersResistor and Capacitor Layout TheoryMagic tool BasicsResistor Layout demoCapacitor LayoutInverter and switch layout LIVE LabsInverter layout startingInverter Layout ContinuedInverter Layout CompleteSwitch Layout startingSwitch Layout Complete10-bit DAC layout design and post-layout analysis2Bit DAC to 10Bit DAC starting2Bit DAC to 10Bit DAC CompleteOutput Response EvaluationDNL and INL theoryDNL and INL Calculations
