Overview

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
