A 10-Gb/s 0.71-pJ/bit Forwarded-Clock Receiver Tolerant to High-Frequency Jitter in 65-nm CMOS

Abstract

This brief presents a power-efficient forwarded-clock receiver that is tolerant to high-frequency jitter by mixing filtered clock jitter to data. Due to mixing the filtered clock jitter, the proposed receiver does not include power-hungry delay lines but a phase interpolator, which enables saving significant power consumption. In a prototype receiver implemented in a 1-V 65-nm complementary metal-oxide-semiconductor process, it removes 2-GHz 0.7UI jitter modulated in data by an amount of 22%. It achieves 10 Gb/s with 0.71 pJ/bit in 10-cm FR4 channels and occupies 0.012 mm(2).
