Objectives
Provide the student the ability to use analytical techniques in the design techniques of analog integrated circuits operating with low-voltage supply (i.e., smaller than the sum of the absolute values of the threshold voltages of the NMOS and PMOS devices), namely advanced topologies of amplifiers, of comparators and of switched-capacitor circuits employing clock-bootstrapping and switched-opamp.
Prerequisites
Approval in the Courses of Nanocircuits and Analog Systems (NSA), and Electronics I and II.
Subject matter
The course can be divided into 5 macro modules:
- Evolution of the roadmap of CMOS technology and major limitations imposed by the reduced supply voltage (e.g., degradation of the signal-to-noise ratio, degradation of transistors’ matching, problems in using more than 3 devices in stack, etc.);
- Advanced topologies of amplifiers and comparators employing positive-feedback schemes and able to operate at low supply voltages;
- Techniques for switches’ linearization (‘clook-bootstrapping’ circuits, switch-linearization circuits (SLCs), etc.);
- The switched-opamp technique;
Case studies from the state-of-the-art.

Teaching method
Theoretical exposition and analysis of case-studies: through a series of lessons (with profile working session) that promotes the participation of trainees. The exhibition is supported in written information on the blackboard, with synchronized slides. Multimedia components, including animations, as well e-learning from platform Moodle @ FCT. Each topic is supported with the analysis of real cases.
Hands-on project.
