The student will after the course understand analog electronic circuits and how they can be designed with components such as operational amplifiers and transistors. The student will be able to individually dimension, simulate, build and test a low frequency.
For a passing grade the student shall be able to:
define and calculate gain, input and output impedances for amplifiers based on operational amplifiers and transistors and choose suitable amplifier configuration
determine transfer function for frequency dependent amplifier circuits, draw bode plots (magnitude and phase) and calculate frequency bandwidth
describe the function and explain the characteristic data for operational amplifiers, diodes and transistors
define the concepts of feedback and explain why feedback amplifiers can be unstable
design simple RC-oscillators with operational amplifiers
describe current-voltage characteristics and large signal models for diodes and the bipolar and MOS type of transistors and calculate the small signal parameters for transistors and use small signal models
verify designs with SPICE simulation program and build a prototype and by measurements evaluate the performance of analog circuits
For a higher grade the student shall be able to:
analyze effects of offset voltage and input bias currents in operational amplifier circuits and determine if compensation is needed
calculate stability margins for feedback amplifiers and dimension compensation networks for potentially unstable amplifiers
create models for analog amplifiers and out of that derive gain, input and output impedance
calculate the way the high frequency model of a transistor influence an amplifier circuit
