Design of Electronic Devices
FEKT-BPC-KEZAcad. year: 2019/2020
Design and properties of signal lines, supply lines and distribution frames - suppression of interference and ground loops.
Parasitic events and their suppression - coupling in input and output circuits, parasitic capacitances and inductances, thermoelectric voltage, overvoltage on inductive load, reflections on lines, crosstalk. Electric and magnetic field screening, equipotential guarding. Choice of components and application recommendation - discrete elements, operational amplifiers, comparators, electronic switches, A/D and D/A converters, sample-and-hold elements, digital circuits, microprocessors. Mechanics design: regulation, control and indication elements - lay-out on the front panel, instrument housing design, heat removal, thermostatic elements. Printed circuits, wired printed circuits, connection of conductors and components. Safety requirements in instrument design. Methodology for the debugging of electronic device.

Assesment methods and criteria linked to learning outcomes
Up to 20 points can be had for design exercises. Part of the design exercises can be in the form of individual project. The examination proper is a written examination and up to 80 points can be awarded for it. The examination is focused on testing the knowledge of application principles in the design of electronic instruments, from the viewpoint of both electronic and mechanical solutions.
