This course focuses on phase locked loops (PLL) theory and behavioral modeling. PLLs are one of the most important blocks in RF communication transceiver systems. PLL systems exist in variety of high frequency applications, from simple clock circuits, to local oscillators (LOs) for high performance radio communication links, and ultra-fast switching frequency synthesizers in vector network analyzers (VNA). This course explains different types of PLLs with detailed explanations on individual sub-blocks. It includes PLL design and calculations with lots of examples and homework. There are also system level simulations and behavioral design using Advanced Design System (ADS) software. Phase noise of PLL is discussed in this course using equations, systems analysis, and there are tutorials that guide you to simulate the behavioral phase noise model of PLL and observe the system impact on VCO phase noise. There are also discussion about fractional PLL concept and features in this course.
