DESCRIPTION:The tutorial starts with a basic/introductive overview of moder
 n frequency synthesis techniques\, delivering basic operation theory in an
  intuitive fashion. A point of attention is in this context brought to rec
 ent subsampling PLL architecture. This architecture overcomes the performa
 nce boundaries typically encountered in classical implementations and is r
 edefining today’s state-of-the state of art in frequency synthesis. We w
 ill try to explain why. The following part of the tutorial explores the su
 bsampling loop in context of state-of-the art fractional synthesis and pha
 se modulation. We show how to enable fractional-N multiplication modes\, w
 hile retaining benefits of low-noise subsampling operation. This can be ac
 hieved by introducing digital-to-time converter (DTC)-based time domain si
 gnal processing. We will discuss potential limitations of this block\, and
  how to overcome them in the analog\, or in the digital domain. The versat
 ility of the DTC-based subsampling PLL will further be discussed in contex
 t of phase/frequency modulation\, which is crucial for accurate polar sign
 aling. We will investigate classical loop-bandwidth limitations and explor
 e how two-point modulation principles can elegantly be applied in context 
 of the explored loop. We will openly discuss potential weak-points of this
  environment – and how to address them. This talk insists on an intuitiv
 e\, rather than a strict\, mathematical approach to PLLs. It starts from t
 he basic concepts and then gradually expands in complexity\, while clearly
  highlighting the key ideas and pointing to state-of-the-art embodiments.\
