Nanocircuits and Analog Systems

Objectives

Provide the student the ability to use analytical techniques in the design techniques of integrated circuits, including classical topologies and advanced amplifiers and analysis of transfer functions of circuits realized using switched-capacitor (SC) techniques.

Understanding CMOS technology, its potential and limitations. Learning the equations governing the MOS devices in its various operating regions, the optimal polarization schemes, as well as their small signals models at low and mid/high frequencies. Understanding body-effects, channel-modulation effects channel and short channel effects in MOS devices. Acquire the basics of noise in electrical circuits.

 
Learn how to analyze SC circuits in the discrete time domain and know how to analyze and design 1st order filters employing SC techniques. Understand the adverse effects associated with signal dependent charge-injection and clock-feed-through, as well as the techniques used to minimize them.

Teaching method

The basic concepts and techniques used in analog circuits are explained in theoretical classes, using the board as well as some slides.

In the laboratory classes, the students evaluate their acquired knowledge through the analysis and design of analog circuits, autonomously. They design, optimize, size and simulate two amplifiers using MATCAD and SPECTRE (CADENCE), respectively.

Evaluation method

The final evaluation is calculated using the grades of two laboratory works carried out in groups of 3 students and the grades of either 2 individual TESTS (NT) or a single final exam. 

 NF=(0.3*NLab+0.7* (NT ou NE))

NT=(0.7*NT1+0.3*NT2)

NE = Exam Grade

NT = Tests (final) Grade

Subject matter

The course is divided into 5 macro modules:

-        Design of CMOS Amplifiers;

-        Types of noise, sampled-noise (kT/C) and calculus of the excess noise fator of a CMOS amplifier;

-        Analysis and design of switched-capacitor circuits in the discrete time-domain;

- Analysis and design of switched-capacitor filters.
