A 50-Gb/s Multicarrier Transmitter Using DAC-Based Polar Drivers in 22-nm FinFET

A 50-Gb/s Multicarrier Transmitter Using DAC-Based Polar Drivers in 22-nm FinFET 150 150

Abstract:

A digital-to-analog converter (DAC)-based polar transmitter (TX) is proposed for multicarrier signaling in wireline applications. The proposed TX achieves a 50-Gb/s total data rate with maximized spectral efficiency by using three parallel 5-GS/s DAC-based drivers and two orthogonal carriers of 5 and 10 GHz. The three DAC-based drivers operating …

An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS

An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS 150 150

Abstract:

This article presents a coherent ultra-wideband (UWB) receiver architecture based on a quadrature hybrid correlation (QHC) method that significantly reduces the digital-correlation-relevant power in the conventional standard-compliant UWB receiver. The proposed QHC receiver front end employs analog correlation, two-step synchronization with a digital-assisted path, and time-interleaved (TI) sampling methods for …
