Antonio José GINES ARTEAGA, TIMA Laboratory, RMS team,

Theme: Advanced Computer Aided Design Methodology for RF @ AMS (Analogue Mixed-signal) Circuits and Systems
Date: Oct. 15th, 2015 (Thursday) - 13:30 to 17:15, TIMA Laboratory - Room T312


Antonio J. Ginés graduated in Physics (Electronics) in 2000 at the University of Seville (Spain) and joined the Instituto de Microelectrónica de Sevilla (IMSE), where he is currently engaged in research and design for industrial applications.
In July 2008, he earned a Ph.D. degree in Microelectronics in the topic of design methodologies and calibration for Pipeline ADCs, also from the University of Seville.
Through his working live, he has participated as senior analog mixed-signal designers in several academic and industrial projects. In 2006-2007 he participated as main AMS designer of IMSE in the REMS meteorological instrument, which has been satisfactorily validated in the NASA Mars Curiosity rover. Since 2010 he has been the design leader in two industrial projects with the European Space Agency (ESA), managing a working team of ten designers (AMS/Digital).
During three years he has also participated as external consultor in Anafocus (fabless company for sensor and vision systems designs, recently bought by E2V).
His current research interests include the design, modeling and testing of CMOS analog mixed-signal circuits, high-speed high resolution data converters with digital foreground/background calibration, aero-space applications, and RF front-ends for wireless communications.


Overview: This seminar presents a top-down bottom-up methodology for AMS (Analogue Mixed-signal) circuits and systems, and its application for the automatic synthesis at both transistor and system levels. This methodology has been satisfactorily validated in multiple prototypes and industrial products developed in the “Instituto de Microelectrónica de Sevilla (IMSE US-CNM-CSIC)” for several customers, including NASA, ESA or ADD (bought by ATMEL).
In this seminar the methodology is illustrated with some cases-of-study and technical demos.
We will start with basic structures to clearly show the key concepts; for instance, performing the automatic sizing of a single-ended two stages op-amp with Miller compensation, and its verification within the DesignFramework II from Cadence.
Then, the extension to more complex systems is also introduced with the high-level synthesis of: 1) a 1.8V 0.18mm 15-bit 100Msps Pipeline ADC, and 2) a 1.2V 90nm 2.4GHz ZigBee Receiver.
In all the cases, the importance of modelling will be highlighted.

Attendant skills: analog mixed-signal and system-level designers; previous knowledge on analog design is recommended for basic building block sizing, but no for system level optimization.

CAD tools (in the demos): MATLAB for numerical evaluations, Mathematics for model development (symbolic analysis), DesignFramework II (DFII) from Cadence for transistor-level verifications.
Additionally, we will use skill functions for the communication between MATLAB and DFII.
