Syllabus
Prerequisites: In order to understand some parts of the course contents it is raccomended that the student has a basic understanding of signal processing, espcially in the dicrete-time domain case. The student will also take advantage of basic knowledge of analog integrated circuit design, which tipcally is achieved from the course "progettazione di circuiti integrati analogici"
Target skills and knowledge: The main aim of the course is to study and to make direct experience through the laboratory activity of a typical analog integrated circuits design flow. Therefore, the student will learn the basic architectures and the most efficient circuit solutions for typical analog blocks, such as filters, data converters and frequency synthesizers. Such a knowledge will make the student able to evaluate which solutions are the most appropriate in order to realize an analog electronic system, taking into account the application and its peculiar specifications.
Examination methods: The course makes extensive use of a computer-assisted design laboratory and the student will be asked periodically to solve design problems. Such an activity is a mandatory part of the exam procedure. In addition the student must take an oral exam.
Assessment criteria: As mentioned previously, the student is evaluated on its ability to solve the practical design problems proposed within the laboratory activity. Homework laboratory are assigned weekly and the student will show his work to the instructor directly in the laboratory after one week. The evaluation is based on the following criteria: (1) capability of applying the design solutions discussed during the lectures; (2) level of insight with respect to the proposed solution; (3) ability to critically evaluate the simulation results; (4) ability to choose the most appropriate design trade-off; (5) clarity and precision in the explanation of the chosen solution.
The laboratory activity will contribute to the 60% of the final grade.
During the oral exam, the candidate will be asked to describe some of the topics covered during the classes and will be evaluated on the basis of the following criteria: (1) clarity and precision in the explanation; (2) insight gained with respect to the topic; (3) ability to critically evaluate and compare different solutions and/or design trade-off, taking into account the desired specifications.
Course unit contents: Definition of basic figure of merits for analog circuits: noise floor, dynamic range, dependence on process parameters spread and sensitivity. Effects of non-linearities in active circuits: power series approximation, harmonic distortion, intermodulation products. Figure of merits related to the non linear behavior: HD, THD, IM. Desensitization of a receiver front-end and two-tone test.
Approximation methods to synthesize an analog filter with a given transfer function. Realization of a second-order filter (biquad) using a cascade of integrators. Efficient implementation of the integrator using an integrated CMOS technology: MOSFFET-C and Gm-C. Effects of the main circuit non-idealities: finite gain and bandwidth, equivalent non-linear resistance of the MOS transistor, sensitivity to process parameters spread.
Switched-capacitor filters. The concept of a switched capacitor. Switched capacitor integrator and its sensitivity to parasitic capacitors. Effects of the main circuit non-idealities: finite gain and bandwidth and slew rate of the OTA, parasitic resistance and capacitors of the MOS switches, thermal and Flicker noise.
Analog-to-digital converters. Definition and characterization of quantization noise. Converters figure of merits: SNR, SNDR, THD, DR, INL, and DNL.
Flash converters: architecture, circuit realization of the comparators considering gain and bandwidth limitations and DC offset.
Pipeline converters. Multistep conversion concept and pipelining. Circuit realization of the basic stage. Effects on the global converter of gain errors, mismatch and comparator offset. Calibration techniques.
Sigma-Delta converters. Oversampling and noise-shaping concepts. Sigma-Delta architectures and trade-off between order, oversampling ratio and number of bits on the internal quantizer. Effects of the main circuit non-idealities (finite gain and bandwidth, thermal noise) and power-efficient design criteria. Mash architectures. Introduction to the decimation filter.
Frequency synthesizers. Introduction to typical RF receivers. Phase locked-loop (PLL): introduction and analysis in the lock state. Trade-off between bandwidth and precision: type-I and type-II PLL. Examples of circuit realization of a PLL. Main noise source in a PLL and optimal choice of the loop bandwidth in order to reject the oscillator phase noise. Integer N PLL. Introduction to fractional PLL with sigma-delta modulation.
Planned learning activities and teaching methods: About 2/3 of the course is based on a classical class teaching, using slide projection. The rest of the teaching time is spent directly in the CAD laboratory, where the student can make direct experience of circuit design and verification, under the supervision of the instructor that can lead the student in the learning process.
Additional notes about suggested reading: All the slide projected during the class are available in advance for the students. It is worth to mention that the course introduces the student to the state-of-the-art of classical analog building blocks, therefore the reference material is composed of scientific papers instead of a classical text book: in such a way the student is always exposed to up-to-date reference material. The most relevant papers are also discussed with the teacher during the classes.
