Abstract :
A very simple, low power, wide range and high accuracy Phase Detector (PD) is presented solving many problems of the conventional circuits. SPICE simulation results show that the immune frequency range of operation is 1MHz to 2GHz. The dead zone of the presented open loop PD is zero, makes it the best choice to be used in high speed DLLs. This circuit is tested in 0.35um CMOS technology.
