AbstractThis course teaches the basics of analog chip design and layout with an emphasis on neuromorphic circuits, which are introduced in the fall semester course "Neuromorphic Engineering I".
ObjectiveDesign of a neuromorphic circuit for implementation with CMOS technology.
ContentThis course teaches the basics of analog chip design and layout with an emphasis on neuromorphic circuits, which are introduced in the autumn semester course "Neuromorphic Engineering I".

The principles of CMOS processing technology are presented. Using a set of inexpensive software tools for simulation, layout and verification, suitable for neuromorphic circuits, participants learn to simulate circuits on the transistor level and to make their layouts on the mask level. Important issues in the layout of neuromorphic circuits will be explained and illustrated with examples. In the latter part of the semester students simulate and layout a neuromorphic chip. Schematics of basic building blocks will be provided. The layout will then be fabricated and will be tested by students during the following fall semester.

AbstractThis course will teach the basics of digital electronics, to give students hands-on experience with using COTS (Commodity Off The Shelf) components to build their own systems. It covers embedded microcontroller programming, logic design on FPGAs, PCB design and assembly.
ObjectiveThe basic aim is to remove the fear of starting and offer the students a first experience at many levels of design.
ContentThe course consists of short lectures on theory and exercises using two different hardware platforms - a microcontroller board with Universal Serial Bus (USB) interface, and a Field Programmable Gate Array (FPGA) board. In addition the course includes exercises in printed circuit board (PCB) design and PCB surface mount assembly. Students will complete a project of their own design which they can take with them after the course ends.

Week 1
Introduction and organization

Prerequisites / NoticeThe course is meant to complement the analog course by teaching how to build systems that convert and process analog information.

Students should have taken Analog Electronics for Physicists or equivalent and should have had some programming experience, preferably with C. Students (or at least each group of 2 / 3 students) need a laptop computer, preferably Windows or Linux. Windows (real or virtual) is required for the FPGA part of the course.
