Theoretical Studies of Sub-THz Active Split-Ring Resonators for Near-Field Imaging
Ali Ameri, Jun-Chau Chien, Ali M. Niknejad
This paper develops a theoretical framework for the design of Active Split-Ring Resonators (ASRRs). An ASRR is a Split-Ring Resonator (SRR) equipped with a tunable negative resisto…
Spatial IDFT for Squint-Free Massive Arrays
Hesham Beshary, Ali Niknejad
This paper presents a novel technique to build squint-free massive phased arrays. This is accomplished by explicitly implementing a spatial IDFT to cancel out the DFT imposed by th…
Design of Linear Passive Mixer-First Receivers for mmWave Digital Beamforming Arrays
Rawan Al Kubaisy, Sashank Krishnamurthy, Ali Niknejad
A 25-40GHz passive mixer-first receiver using a novel architecture for digital beamforming arrays is proposed. The architecture uses a novel technique for impedance matching using…
Compact Device Models for FinFET and Beyond
Darsen D. Lu, Mohan V. Dunga, Ali M. Niknejad +6
Compact device models play a significant role in connecting device technology and circuit design. BSIM-CMG and BSIM-IMG are industry standard compact models suited for the FinFET a…
Optimizing the LO Distribution Architecture of mm-Wave Massive MIMO Receivers
Greg LaCaille, Antonio Puglielli, Elad Alon +2
Wireless networks at millimeter wavelengths have significant implementation difficulties. The path loss at these frequencies naturally leads us to consider antenna arrays with many…
