Short Description

Various aspects of a frequency synthesizers have been widely investigated for several decades, such as output phase noise, output frequency range, locking time, supply rejection, tolerance to variabilities, spur minimization and input noise rejection. Consequently, numerous innovations have been introduced for improving the performance such as sub-sampling PLL, Multiplying DLL, replica-biasing, DSM noise cancellation, digital-to-time converter based fractional-N synthesis, injection locking and so on. Therefore, a recent frequency synthesizer is highly well-optimized so that its performance is closed to the theoretical limits. In this project, students will learn the key techniques for an advanced frequency synthesizer by designing a frequency synthesizer specific to the application requirements.
