This course outlines the complexities of mixed-signal integrated circuit design. Especially, we discuss analog and mixed-signal integrated circuits and their application in a system-on-chip environment. Most often, nowadays, this implies a communication system-on-chip. The analog and mixed-signal circuits are used for modulation and demodulation of the digital signal. We need amplifiers, mixers, PLLs, DLLs, filters, and data converters to transmit and receive an analog signal carrier.
In this course, we focus on the intermediate frequencies and baseband. RF aspects are not covered.
Due to the scaling of transistors, digital circuits can be implemented with higher density and due to the highly advanced computer tools, the operation of the digital circuits can be more advanced and reliable. For analog and mixed-signal circuits this does not really apply. Most of the work still has to be done by hand and we also do not have a direct "digital" measure of success. Instead, we have to investigate the noise and linearity of the analog circuits as metrics of error and functionality.
We design amplifiers for wide frequency bands. These amplifiers are then used in line drivers, filters, data converters, etc. The student will get an insight in the large complexity of designing analog and mixed-signal integrated circuits. The design issues in this course mostly focus on the circuit-level aspects. Layout and similar important topics related to IC design are covered by other courses.
