Analog to Digital Converter Modelling with PySpice

Author: Olzhas S. Tazabekov (LinkedIn)

Prerequisites: basic programming skills with Python and SPICE

Intro

This is the second tutorial of the series dedicated to IC modelling with PySpice. Or how to not spend tons of money on CAD licenses for those half starving tech startups, so that the board members could keep their kidneys 😉 This tutorial will continue the discussion of modelling data converters and their components and will describe how to model an Analog-to-Digital Converter (ADC). Some of the DAC code and concepts covered in the previous article will be used here as well.

Digital to Analog Converter Modelling with PySpice

Intro: Why is All the Buzz

Throughout our University degree programs, we all learned how to analyze, design and verify electrical circuits. Unfortunately or fortunately, most of us were trained using industry level graded software (e.g. Cadence, Synopsys, etc.). However, in real life (outside of school) that software does come with a pretty heavy price associated with the cost of licenses and IT infrastructure. So, unless you are heavy weight semiconductor giant with millions in corporate accounts it is a quite a challenge to afford. Where does this leave all those half starving tech startups or ordinary people? Open source software has been one of the answers so far (another one is to sell a kidney of one of the board members and purchase an IC design tool license 😉 ). Continue reading
