Digital and mixed-signal circuits

Lab Practice

The practical laboratory training deepens the lecture content in several practical experiments and is divided into two subject areas:

  • First, digital circuits are constructed and tested from standard logic circuits (plug-in module system) and by means of programmable logic (PLD). The design process is carried out both classically and with the help of hardware description languages (VHDL). Starting with simple combinatorial basic circuits, further complex sequential digital circuits are developed and realized and their time behaviour is investigated.
  • We then turn to the structure and functionality of mixed-signal circuits using the example of various analog-to-digital converters. We get to know the circuit-technical realization of all important conversion processes: Tracking, SAR, parallel and delta sigma procedures. For practical implementation, we rely on both simple solutions with standard circuits and complex VHDL designs in CPLD and FPGA applications.
