Design and verification tasks to employ new digital solutions for the future low-power low-area sensor products.

Lausanne, Vaud, Switzerland

Engineering work related to the design, verification, layout, and measurement of DRAM-related circuits. The development of a Gain-Cell embedded DRAM macro has shown to provide several benefits over its static counterpart. Due to its smaller area footprint, this technology allows the integration of much more on-chip memory compared to classic SRAM macros. This advantage is very important in memory-hungry applications such as AI, IoT, 5G and automotive.

The topic of the thesis involved providing solutions to minimize power consumption in Gain-Cell embedded DRAM memories. Analog and mixed signal circuit solutions have been designed to reduce the refresh power consumption of the embedded DRAMs by over 1000 times. Moreover, built in self-test (BIST) and built in redundancy analysis (BISR) functions have been developed to replace faulty bit cells by redundant cells in order to improve power consumption and yield. Keywords for this work were low power and low area overhead circuit design.

Zurich, Switzerland

Seven-month internship in collaboration with IBM Watson Research Lab, working on the design of cryogenic CMOS circuits to be implemented in the next generation of quantum computers. The analog front-end together with the digital back-end have been designed in advanced Fin-FET nodes, taking into consideration physical device effects happening at cryogenic temperatures. A part of the internship also involved performing RF measurements of previously taped-out ICs for comparison of circuit performance between room temperature and cryogenic temperatures.

Internship in the BIOROB lab of EPFL. My tasks consisted in doing PCB designing, microcontroller programming and PCB manufacturing on a robot localization system for EPFL’s interdisciplinary robot competition.

Lausanne, Vaud, Switzerland

Teaching assistant for the course "Logic systems" taught to second year bachelor students in the micro-engineering faculty of EPFL.

Lausanne, Vaud, Switzerland

My role was to provide assistance to two groups of four apprentices with difficulties in electrotechnics and math. The challenging part is to explain concepts that seem simple to young people that have difficulty in a specific subject.

Bellinzona, Ticino, Switzerland

Experience gained during the apprenticeship. Most of the work was dedicated to PCB prototyping (Altium) and manufacturing, microcontroller programming in C, and other general lab work such as troubleshooting electronic devices.
