Course program
The course will give the
basic theory of Sigma-Delta modulation. Different ΣΔ structures and
relative performance for A/D conversion. SC and continuous-time implementation
comparison. Design & simulation. Stability. ΣΔ structures for
D/A conversion.
- The quantization noise. The oversampling and the noise shaping
- The 1st order ΣΔ modulator: Signal & Noise transfer function. Transient behavior. SNR vs. OSR. DC input and Tone generation
- The 2nd order ΣΔ modulator. Signal / Noise transfer function. SNR vs. OSR. Performance limitations
- Switched-Capacitor implementation of SD modulators
- High-order ΣΔ modulator. SNR vs. modulator order. Single loop structure. Mash structure
- Bandpass ΣΔ modulator
- Design and simulation of ΣΔ modulator:
- The Schreier’s and the Brigati’s MATLAB tool boxes.
- Decimator filter
- Oversampled DAC

Andrea Baschirotto has a long-term
experience in microelectronics for what concerns teaching, researching, and
industrial designing.
He is teaching regular Academic courses since 1997. He organized the full educational courses for Electronics Engineering (Bachelor, Master, and Ph.D.) at University of Lecce. He uses to give industrial courses since 1996 (in Bosch, STMicroelectronics, ITC-IRST, Conexant, Mikron, etc…). He is a speaker at the MEAD Summer courses held at EPFL (Lausanne – Switzerland). He uses to give short courses or tutorial at the most important conferences (ISSCC, ISCAS, PRIME).
About his research activity, he
founded and he is leading the Microelectronics Group at University of Lecce,
which is collaborating with several companies and research institutions (IMEC,
Infineon, University of Pavia, RFDomus, STMicroelectronics, etc….). His main
research interests are in the design of CMOS mixed analog/digital integrated
circuits, in particular for low-power and/or high-speed signal processing. He
participated to several research collaborations, also funded by National and
European projects. He is/has been responsible of some National and Regional
projects for the design of ASIC. Since
1989, he also personally collaborated with several companies on the design of
mixed signals ASICs, like STMicroelectronics, Mikron, ACCO, ITC-IRST, RFDomus
(now GloNav), Conexant, etc….
Andrea Baschirotto was Associate
Editor IEEE Trans. Circuits Syst. – Part II for the period 2000-2003, and he is
now serving IEEE Trans. Circuits Syst. – Part I as an Associate Editor. He has
been the Technical Program Committee Chairman for ESSCIRC 2002 and he was the
Guest Editor for the IEEE JSSC for ESSCIRC 2003 and ESSCIRC2007. He was the
General Chair of IEEE-PRIME2006 and AACD2008.
He is the member of the Technical Program Committee of several international conferences (ISSCC, ESSCIRC, DATE, etc..). He is serving since several years the ESSCIRC TPC as Data Converter Subcommittee Chairman. He has been the secretary of the European Committee of ISSCC Technical Program Committee. He is an IEEE Senior member. He is the founder and the Chairman of the IEEE Solid-State Circuit Society Italian Chapter.
