Description
The webinar aims to circuit design of a 10-bit potentiometric Digital to Analog Converter, from scratch, using Xschem and Sky130 PDKs. The target is to design 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 1" conducted by Skandha Deepsita
In 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.
