 Aims
 body { font-size: 9pt; font-family: Arial } table { font-size: 9pt; font-family: Arial } For the electronics part, after this module the student should be able to:   Know how to bias a BJT and a MOSFET and understand the limitations of the different bias circuits with respect to variations in temperature and component properties. Be able to 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. Know the basic one transistor stages and their gain and input- and output impedances, and use this knowledge to choose and combine appropriate stages. Know and be able to analyze the effect of feedback on circuit properties like gain, bandwidth, distortion, input impedance and output impedance. Be able to analyze the stability of feedback circuits by Nyquist plots and bode plots of the loop gain.
 Content
 body { font-size: 9pt; font-family: Arial } table { font-size: 9pt; font-family: Arial } This study unit deals with the analysis and design of circuits on transistor level. Using large signal models of both bipolar transistors and MOSFETs, we will first investigate different ways to bias a transistor. Given the proper bias point, we will then derive and use two-port analysis and small signal equivalent circuits to work in the frequency domain and analyze properties like input impedance, output impedance and gain as functions of frequency. Basic one-transistor amplifier stages are introduced with their main properties. By combining different stages, more complex amplifiers can be built that satisfy certain specifications. Another topic in this study unit is feedback. We start with ideal opamps and gradually extend with opamp non-idealities like input- and output impedances and frequency dependent gain. This has an influence on the stability and we will need Nyquist plots and Bode plots of the loop gain to assess the stability and use this to design stable circuits. In the Electronics project (202200178) everything will be combined by designing and building an audio power amplifier.
