Phase Frequency Detector without dead zone
Jun 30th, 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 ?
