Analog Circuits


The microelectronics department has very well equipped laboratory workstations. Two students work effectively per workplace. A laboratory workstation includes the following equipment:

  • Function generator (up to 6 MHz)
  • Dual channel oscilloscope (up to 20 MHz)
  • Digital multimeters and adjustable power supplies
  • personal computer

A plug-in module system is available for test setups. This is used to set up and test both analog and digital circuits in laboratory training.

To simulate electronic circuits, students learn how to use the current version of the LTSpice program package.

In digital circuit technology, students are familiarized with an integrated development system for freely programmable logic circuits from XILINX (Field Programmable Gate Arrays). The development system includes graphical input tools (schematic, VHDL, automatic graph, and Boolean equations), digital simulators, bit pattern generators and analyzers, implementation tools, and a hardware test environment.

For further tasks (e. g. student research projects and diploma theses) the chair has high-quality measuring technology at its disposal, e. g.

  • 500 MHz digital oscilloscope
  • spectrum analyser
  • freely programmable signal generator up to 15 MHz

A printed circuit board design system is used to realize prototypes of our own developments. This includes a PCB editor with Autorouter and a CNC milling machine for the isolation engraving of printed circuit boards. Both conventional and SMD assembly is possible at our soldering workstation.
