By the end of the course, the student can: |
1. Explain how to model components like a diode and analyze circuits using those models. Important aspects in this include estimation of validity ranges for the model.
2. Explain the basics of the physical operation of non-linear components such as the BJT, and know how to bias a BJT and explain the limitations of the different bias circuits with respect to e.g. variations in temperature and component properties.
3. transform a transistor circuit to its small signal equivalent form, analyze its behavior and make a bode plot of small signal properties like gain and in- and output impedances.
4. Analyze basic single transistor stages and derive their gain and input- and output impedances, and use this knowledge to choose and combine appropriate stages.
5. Analyze the effect of feedback on circuit properties like gain, bandwidth, distortion, input impedance and output impedance.
6. analyze the stability of feedback circuits by Nyquist plots and bode plots of the loop gain.
7. Explain the workings of an oscillator and determine its oscillation criteria.
8. Explain the basic workings of an antenna and be able to match it to a circuit whenever required.
9. design, simulate, build and measure circuits with transistors according to a given set of specifications.
10. Apply this knowledge and these skills to design, build, measure and demonstrate a (~100MHz) wireless audio link.
This electronics course starts with an introduction into modeling of non-linear components and an introduction into semiconductor physics of diodes, bipolar transistors. This is subsequently used for analysis and synthesis of basic analog circuits. These analog circuits are then extended into systems with feedback to create well-behaved stable circuits and well-behaved oscillators. The last part of the course presents an introduction into (radio frequency) transmitter systems, more complex analog circuits and digital electronics. The material is presented in the form of lectures/exercise classes and labs/projects. The final project of this module is the design, realization and characterization of an RF-transmit-receiver system to transmit audio wirelessly; this project is done in small groups, and includes peer review.
