Phase Frequency Detector without dead zone
Jun 30

, 2019, 1:12am
How does the two inverter delay stage in Figure 6.14 on page 265 of
Design of CMOS RF Integrated Circuits and Systems
helps to eliminate dead zone in Phase Frequency Detector ?
The book version adapts the original version (
Cell-Based Fully Integrated CMOS Frequency Synthesizers
) with slight modification.
Any idea why the book version does not require the feedback signal of DOWN signal ?
