Abstract

Phase Frequency Detectors (PFD) are the most important components of Phase Locked Loops (PLLs) which gives an output that is linearly proportional to the phase difference of the reference signal (CKR) and output of VCO (CKF) [8]. PFD has a number of applications in communication systems, wireless sensors, and robotics. Some application are focused on the efficiency or bandwidth, some other on low noise and jitters or it can be its size. In this paper, effect of scaling on a latch based PFD is presented. This paper presents the compassion of various technologies using different channel lengths and is useful to determine which is the best suitable channel length having best characteristics. Various technologies of CMOS are used and the performance is considered on the basis of two parameters-power consumed and delay in output when input is already given. The authors have used Tanner EDA 14.11 version on various technologies.
