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;


Attendance will be strictly enforced and those falling short will not be permitted to write the end sem exam. TAs will go around the room taking attendance at the beginning of the class. If you are more than 5 min. late, please do not enter the classroom.
