Circuit Design


Campus Offenburg, room B 101

Profile and objectives

The laboratory for electronic circuit technology complements the lectures "Analog circuit technology I + II" and "Digital circuit technology I+II", in which students have the opportunity to "understand" the most important circuits through practice. In addition, the use of modern electronic measuring instruments such as storage oscilloscope and logic analyzer will be practiced. Furthermore, modern methods of circuit analysis with the aid of computers will be learned. The circuits are kept simple to allow a complete penetration of the problem within the available time. The laboratory takes place in the 5th semester.

The laboratory for circuit technology includes the laboratory for SMD technology, in which high-quality SMD printed circuit boards can be designed, assembled and tested. Due to the personal union of the head there is also a very close cooperation with the ASIC laboratory of the FH, where high-quality layouts are designed and the aspects of the integration of electronics are considered.

Internships and Tutorials

The student works on a selection of 6 experiments from the following experimental set-ups:

  • Operationsverstärker
  • SPICE - Simulation of a differential amplifier
  • combinatorial circuits
  • design of PAL/GAL - components
  • investigation of A/D - converters
  • Phase Locked Loop (PLL) measurements
  • Digital simulation of a synchronous counter
  • use of ECL technology
  • construction of a sample circuit in SMD technology
  • development of FPGA devices (ALTERA)

In the laboratory, student research projects and diploma theses are constantly carried out on the following topics:

  • general circuit development analog/digital
  • embedding of microcontrollers in circuits including programming in assembler,
  • design of FPGA and GAL devices in connection with the above designs,
  • design, construction and commissioning of complete circuit boards including lay-out,
  • system design taking integration possibilities (ASIC) into account

Within the scope of research and development work, extensive projects with complex digital, analog and processor-based electronics are processed, including electronics for CCD linear cameras, broadband IR data transmission and a GPS navigation receiver, partly in close cooperation with other laboratories of the University or industry.
