Learning objectives
Knowledge:
the main goal of the course is to provide the students the knowledge of both theoretical and practical aspects required to design an analog integrated circuit in CMOS technology. In particular:
-theory: advanced analog electronics and architectures of analog circuits in CMOS
-practical: usage of EDA-CAD tools, design techniques and guidelines for analog circuits
Provided skills:
At the end of the course the student is able to:
-find out the most appropriate architecture of the analog block to be designed
-size (W/L,L,R,C, etc.) the device of an analog circuits from the spec.s table
-plan and implement a verification strategy for the designed circuit with advanced EDA-CAD tools
In particular in the part of the course dedicated to the design-lab. each student is required to implement
the theory learned in the oral lessons in the design of analog circuits (i.e. from a single-transistor amplifier to a quartz oscillator).
Prerequisites
Electronic devices (MOS transistor)
Basic analog electronics (the concept of circuit linearization, single-transistor amplifiers, differential amplifier, black-box operational amplifier)
