Objectives
In the field of baseband circuit design, the course will focus the study on two important analog functions: analog-digital / digital-analog conversion, and phase-lock capture.
In the area of analog to digital conversion, and vice-versa, Nyquist and Sigma-Delta type converters are analyzed and projected.
The Phase-Lock Loop (PLL) basic operation is presented based on a linear model valid when the circuit is in lock state.
The student will develop the ability to solve problems, work in a team and autonomously. Students also will learn how to improve their ability to manage the available time. Special attention is given to the ability of written and oral presentation of the work.
Prerequisites
asic knowledge on MOS devices and switched capacitor circuit operation is required.
