Two innovative design techniques lead to substantial improvements in performance in fractional-N phase locked loops (PLLs), report scientists from Tokyo Tech. The proposed methods are aimed to ...

Some brief theory and typical measurements of phase noise. Standard analysis of PLL phase noise used by most CAD applications. How to produce the lowest phase noise at a PLL output. A standard design ...

The 74HC/HCT4046A are phase-locked loop (PLL) with linear voltage-controlled oscillator (VCO) CMOS device having pins suited to 4046 in a 4000B series. These devices comply to JEDEC standard no. 7A.

This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...
