Welcome to the homepage of the Electronic Design group

The Electronic Design group at EISLAB performs research on analog and mixed-signal design for sensor systems, embedded systems, and vehicle electronics. The group covers a wide range of projects, ranging from high efficiency motor drivers, through wireless platforms for sensor networking, down to low-noise transistor design on silicon.

The group has through the Europractice cooperation possibilities to manufacture on-chip designs in a wide range of processes. A well equipped microelectronics laboratory allows chip scale handling and mounting such as die bonding and wire bonding, as well as traditional surface mount technology. The laboratory is also well equipped for on and off chip measurement purposes.

Today there are a number of active research topics within the area of electronic design. These are listed and explained following this link --->

Optoelectronics

The research focuses on distance measuring sensors based on time-of-flight (TOF). The application is mobile robot navigation. Today the work is centered on commercially available devices. One core component is the laser, which is steered by a mechanically rotated mirror. The sensor is a highly sensitive one pixel device with short response time. The systems measures times in the order of nanoseconds, with resolution in the picoseconds range.

High efficiency motor drivers

The research aims at development and design of high efficiency and low interference driver electronics for DC and AC motors. One application of the work has this far been the Baldos student project, where the technology has been introduced in the car since two years. Modeling of the motors is an important part in the work, which is used in research as well as in education on undergraduate level.

Embedded systems

This part develops hardware for very low power, small size embedded systems. The systems are used in research projects and as an applied base for work on software and architecture for embedded systems. Currently applications are found within projects such as iRoad, Socrades, Fjärrvärme and others.

ASIC design

ASIC design is performed targeting extreme low power, small size, sensor front end electronics. Current work includes time sampling ADCs, drivers and amplifiers for ultrasound systems, and optoelectronic sensors. DC/DC converters and high output power DAC for high voltage (50V) have also been designed. Work in progress includes the use of CCDs as analog delay lines to optimize AD converter utilization in low power systems. Through the Europractice cooperation possibilities are available to manufacture on-chip designs in a wide range of processes.
