Description:
This subject provides information about basic electronic devices and sensors, describes their operation principle, basic circuit configuration and application in biomedicine. The stress is aid mainly on clarifying of basic principles and practical utilization. Students are introduces with basic passive electronic devices (resistors, capacitors, inductors), with their design and fabrication and with equivalent circuits and models. The next topic is engaged in basic effects in semiconductors and PN junction operation principle, diodes and their application (rectifiers, stabilizers), bipolar and unipolar transistors (amplifiers, switchers, temperature characteristics), multilayer semiconductor devices for high-power applications, technologies for integrated circuit fabrication and vacuum devices. Integral part of this course is basic information about sensors of non-electric quantities and their read-out circuits eg. strain related sensors (force, pressure, torque, vibration, displacement, acceleration etc.) magnetic field sensors, temperature sensors, chemical sensors, optical sensors and biosensors. The stress is aid on miniaturization, integration and application in biomedicine.
