Abstract: A CMOS Implementation of Time amplifier (TA) based Bang-Bang Phase Frequency Detector (BBPFD) using Sense amplifier based flip flop (SAFF) is presented in this paper using 0.18μm CMOS technology. A time amplifier based on feedback output generator concept is utilized in minimizing the metastability and increasing the gain of TA which in turn boosts the gain of Phase Frequency Detector (PFD). Also, a modified SAFF was built in CMOS 0.18μm technology at 1.8V which further reduces the hysteresis and metastability aspect related to PFD. The proposed PFD works at a maximum frequency of 4GHz consuming 0.46mW of power with no dead zone.
Keywords: Time Amplifier, BBPFD, SAFF.
