Course contents

Digital communication over wired links; Mesochronous and Plesiochronous links; Clock and data recovery circuits for these links; Phase detectors for periodic signals and random data; Phase-locked loop and delay locked loop; Analog and digital implementations of CDRs and PLLs; Channel characteristics-intersymbol interference, eye diagrams; Linear equalization at the transmitter and receiver; Decision feedback equalization; Equalizer adaptation using the LMS algorithm.


To understand and carry out simulations of CDR and PLL circuits, channel models, and equalizers; To be able to determine the parameters of these systems starting from specifications.



  • Basics of continuous-time and discrete-time signals and systems; Basics of transmission lines; Knowledge of MOS transistor basics related to circuit design, small signal equivalent circuits, small and large signal analysis; Design of building blocks-basic amplifier stages, differential pairs, and bias generators;
