Аннотация

In this paper the performance of high speed phase frequency detector (PFD) is analysed. A high-speed PFD reduces the power consumption of traditional PFD to 0.423 nW at 1 GHz clock frequency and dead zone to 2 ps. It is suitable for low power applications. A PFD uses only 18 transistors. This PFD operates up to 1 GHz at 1.2 V supply voltage. The proposed architecture of the PFD has been implemented using 0.35μm CMOS technology and 90 nm CMOS technology.   Keywords: low power PFD, phase frequency detector, phase-locked loop, PLLCite this Article: Nilesh D.
