Single-Course Danish 5 ECTS

Rapid Prototyping of analogue DC Sensor Systems

Overall Course Objectives

The course introduces the student to analogue electrical circuits with the aim of constructing prototypes of DC measuring systems. Electrical circuit theory is used to design amplifier circuits for amplifying weak sensor signals.

Learning Objectives

  • explain and use Ohm’s law and Kirchhoff’s laws to derive circuit equations for voltages and currents in an electrical circuit.
  • explain the basic principles of electrical installations, explain the risks of using and handling electrical installations and equipment, calculate currents through the body in typical electrical accidents and explain the human body’s reaction to different amperages.
  • use nodal and mesh analysis and superposition methods to set up equations for voltages and currents in a circuit.
  • apply concepts such as voltage and current dividers to speed up analysis of electrical circuits.
  • combine sets of linear equations and calculate nodal voltages, branch currents, and mesh currents in passive resistive networks and in resistive networks with operational amplifiers.
  • apply the principles of the ideal operational amplifier to derive systems equations for inverting, non-inverting and summing amplifiers.
  • explain the principles of thermistor, pressure, and light sensors and include these sensors in sensor circuits.
  • calculate component values for an amplifier circuit so that the sensor circuit’s output voltage range is mapped to a new voltage range optimal for digitalization.
  • operate multimeters and oscilloscopes, use KiCad and VeeCAD to simulate circuits and design component layouts on breadboards and veroboards, and use Maple to solve sets of linear equations.
  • build circuits on breadboard and veroboards on the basis of a circuit diagram and validate the construction through systematic search for short circuits and poor/no connections.
  • plan and build a test setup using avaliable testing instrumentation and conduct measurements to validate the performance of an electric circuit.
  • comply with the rules for participation in laboratory exercises, including arriving on time, showing consideration for fellow students, avoiding destroying equipment and components and cleaning up the workplace after the exercise.
