Chadi_Jabbour_SeminarICEABSTRACT
Delta Sigma modulation as its name suggests consists in making a difference followed by a sum. The concept seems simple but this remarkable architecture has been studied and developed for more than six decades and probably will continue to be for six more. Delta Sigma modulators actually can be used for a huge diversity of applications, for Audio Analog to Digital Conversion, for Direct RF wireless transceivers, for high speed optical communications, for controlling Phase Locked Loops, for security applications and much more.
In this seminar, we will present the working principle of Delta Sigma Modulators, their design methodology, architecture innovations, latest implementations and future applications. We will focus mainly on works developed in our team including a predicting ADC for gyroscope applications, a very high speed Digital to Analog Converter for 5G systems and a spatial-temporal TX for massive MIMO applications
Everybody is welcome, the presentation will include RF, analog and digital electronics, optical and MIMO communications, AI also but just for generating the title.
