课程名称：VSD Intern - 基于Sky130的模拟带隙参考设计 课程概述：本网络研讨会详细介绍了通用带隙参考电路的工作原理。课程将重点讲解带隙参考电路的基本工作原理、线路实现及每种实现风格的相关问题。带隙参考电路是一种在温度、工艺和供电电压波动的情况下能够提供恒定电压输出Vref的电路。它是多种模拟和混合信号集成电路的重要组成部分，如线性稳压器（LDO）、模数转换器（ADC）、数模转换器（DAC）和降压转换器等。带隙参考电路提供的恒定输出参考电压为1.2V，这一电压值与硅的带隙能量（1.2eV）在绝对零度（0K）时成正比，因此得名。 本次网络研讨会将涵盖以下内容： - 带隙参考IP的性能参数和电路实现 - 方框图和原理图 - 在系统上下载工具的步骤 - 使用Ngspice进行带隙参考IP电路的布局前仿真 - 温度范围 [-40°C - 140°C] 下的Vbgp与温度的关系（@ RL = 100M欧姆） - Vbgp与VDD的关系（在2V - 4V范围内，@ RL = 100M欧姆） - 温度系数与温度的关系（@ RL = 100M欧姆） - 电压系数与VDD的关系（@ RL = 100M欧姆） - 启动时间（@ RL = 100M欧姆） - 启用时Vbgp的开关电流（@ RL = 100M欧姆） - 使用Magic进行BGR布局 希望您能享受本次网络研讨会。
This webinar provides detail about General Purpose Bandgap Reference. The basic working principle of Bandgap reference circuits is explained. The circuit implementation is discussed and the issues with each implementation style is mentioned. Index Terms-Bandgap Reference, CTAT, PTAT, Current mirror, OpAmp.A Bandgap Reference is a circuit which gives a constant voltage output Vref irrespective of temperature, process and supply voltage variations. It is an especially important component of several analog and mixed signal Integrated Circuits. Several circuits such as LDO, ADC, DAC, Buck convertor. use Bandgap reference as a building block. It provides a constant output reference voltage of 1.2V which is proportional to the Bandgap energy of Silicon(1.2eV)at 0K and hence, gets its name as Bandgap Reference circuitFor detailed information regarding the Bandgap Reference circuit, refer to VLSI System Design website.
