Highly Linear Noise-Shaped Pipelined ADC Utilizing a Relaxed Accuracy Front-End

Creator:: Rajaee, Omid and Moon, Un-Ku
Abstract:: A noise-shaped pipelined ADC is presented in this paper. A minimal complexity ΔΣ modulator in the first two sub-ADCs and residue feedback in the latter stages lead to high-order noise shaping. This also leads to reduced sensitivity to analog imperfections in the front-end stage. Implemented in 0.18μ m CMOS, the...

Ring Amplifiers for Switched Capacitor Circuits

Creator:: Hershberg, Benjamin, Weaver, Skyler, Sobue, Kazuki, Takeuchi, Seiji, Hamashita, Koichi, and Moon, Un-Ku
Abstract:: In this paper the fundamental concept of ring amplification is introduced and explored. Ring amplifiers enable efficient amplification in scaled environments, and possess the benefits of efficient slew-based charging, rapid stabilization, compression-immunity (inherent rail-to-rail output swing), and performance that scales with process technology. A basic operational theory is established, and...

Optimum equalization and synchronization of broadband multicarrier systems

Creator:: Lashkarian, Navid
Abstract:: The application of information theory and digital signal processing techniques to digital communication has resulted in robust methods for reliable high speed data transmission over noisy channels environments. Among these methods, multicarrier systems have become a viable solution for exploiting maximum spectral efficiency over both wideband highly dispersive static and...

Data rate improvements for the IEEE 802.11 wireless local area network standard through the use of code division multiple access and turbo coding

Creator:: Buck, David H.
Abstract:: The widespread use of Wireless Local Area Networks (WLAN) and the desire for such products from different vendors to operate together has generated a movement towards standardization. Over the last decade, several organizations worldwide have researched and developed such standards, this includes the IEEE 802.11 committee. One of the important...

Uplink Performance Characterization and Analysis of Two-Tier Femtocell Networks

Creator:: Chakchouk, Nessrine and Hamdaoui, Bechir
Abstract:: This paper provides a cross-layer analysis of uplink performance in femtocell networks. It characterizes the uplink physical interference in femtocell networks and studies its impact on the delay and data loss rate of constant-bit-rate (CBR) traffic, as well as on the maximum achievable femto-user throughput. Our work derives data-link layer...

Highly Linear, Broadband Optical Modulator Based on Electro-optic Polymer

Creator:: Zhang, Xingyu, Lee, Beomsuk, Lin, Che-yun, Wang, Alan X., Hosseini, Amir, and Chen, Ray T.
Abstract:: In this paper, we present the design, fabrication and characterization of a traveling wave directional coupler modulator based on electro-optic polymer, which is able to provide both high linearity and broad bandwidth. The high linearity is realized by introducing Δβ-reversal technique in the two-domain directional coupler. A travelling wave electrode...

Improved Least Median of Squares Localization for Non-Line-of-Sight Mitigation

Creator:: Qiao, Tianzhu and Liu, Huaping
Abstract:: Non-line-of-sight (NLOS) propagation is one of the major problems that cause errors in localization systems. There exist many algorithms to reduce NLOS caused errors. Most of these algorithms require a priori information about the NLOS links, which limits their application. Least median of squares (LMedS) method is an exception and...

A 0.5-to-2.5 Gb/s Reference-Less Half-Rate Digital CDR With Unlimited Frequency Acquisition Range and Improved Input Duty-Cycle Error Tolerance

Creator:: Inti, Rajesh, Yin, Wenjing, Elshazly, Amr, Sasidhar, Naga, and Hanumolu, Pavan Kumar
Abstract:: A reference-less highly digital half-rate clock and data recovery (CDR) circuit with improved tolerance to input duty cycle error is presented. Using a chain of frequency dividers, the proposed frequency detector produces a known sub-harmonic tone from the incoming random data. A digital frequency-locked loop uses the extracted tone, and...
