The continuous progress in the field of integrated nano-electronic circuits and systems makes it possible to integrate more complex functions with ever-increasing operating speeds in a system-on-chip approach.
The module "High-Frequency Data Converter Techniques" takes up this technological development and focuses on the architecture, design and mode of operation of high-frequency high-precision building blocks such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), phase-locked loops (PLLs) etc. These building blocks are key for application areas like wireless infrastructure applications (e.g. LTE), transceiver systems for electro-optical applications (e.g. Silicon Photonics), power dissipation low sensor systems for biomedical applications (e.g. nerve stimulation) or topics of automotive electronics and Internet-of-Things (IoT).
In this course the following topics are taught
1. High-speed transceiver architectures, wireline receiver and transmitter, equalizer
2. Nyquist rate ADC oversampling ADCs, SAR ADCs, Slope ADCs and their pros and cons
3. SC technology, track - & - Hold Architecturen, Noise Folding, comparators
4. Nyquist rate DAC, oversampling DACs, current-steering vs voltage mode as well as and their pros and cons
5. Programmable Amplifier (PGA / VGA), antialiasing filter
6. Z-transform, discrete fast Fourier transform, resolution, linearity
