A blocker-tolerant, noise-cancelling receiver suitable for wideband wireless applications

D Murphy, H Darabi, A Abidi, AA Hafez… - IEEE Journal of Solid …, 2012 - ieeexplore.ieee.org
A new wideband receiver architecture is proposed that employs two separate passive-mixer-based
downconversion paths, which enables noise cancelling, but avoids voltage gain at …

A blocker-tolerant wideband noise-cancelling receiver with a 2dB noise figure

D Murphy, A Hafez, A Mirzaei… - … Solid-State Circuits …, 2012 - ieeexplore.ieee.org
As narrowband off-chip RF filtering is not compatible with the concept of software-defined
radio (SDR), an SDR receiver must be designed to tolerate large out-of-band blockers with …

…, MZ Eid, MAB Mohammed, A Hafez… - Clinical …, 2012 - Taylor & Francis
Purpose To assess the relationship between postoperative endothelial cell loss and
microcoaxial phaco parameters using Ozil IP (Alcon Laboratories, Inc, Fort Worth, TX) in …

A 32–48 Gb/s serializing transmitter using multiphase serialization in 65 nm CMOS technology

AA Hafez, MS Chen, CKK Yang - IEEE Journal of Solid-State …, 2015 - ieeexplore.ieee.org
A power-efficient transmitter is proposed using a multiphase serializer, multiphase dividers
using injection-locked oscillators, and a high-speed multiplexing structure to relax the timing …

Scalability and design-space analysis of a 1T-1MTJ memory cell for STT-RAMs

…, F Ren, Y Toriyama, AA Hafez… - … on Electron Devices, 2012 - ieeexplore.ieee.org
We present a design-space feasibility region, as a function of magnetic tunnel junction (MTJ)
characteristics and target memory specifications, to explore the design margin of a one-…

A 0.1–1.5 GHz 8-bit inverter-based digital-to-phase converter using harmonic rejection

MS Chen, AA Hafez, CKK Yang - IEEE Journal of Solid-State …, 2013 - ieeexplore.ieee.org
This paper presents a digital-to-phase converter (DPC) with 8-bits of resolution and a wide
frequency range for the input/output clocks. A harmonic rejection (HR) filter is introduced to …
