Feasibility Study of Curvature Effect in Flexible Antenna Arrays for 2-Dimensional Beam Alignment of 6G Wireless Systems
Mahdi Alesheikh, Soheil Saadat, Hamidreza Aghasi
This article investigates the influential role of flexible antenna array curvature on the performance of 6G communication systems with carrier frequencies above 100 GHz. It is demo…
AICircuit: A Multi-Level Dataset and Benchmark for AI-Driven Analog Integrated Circuit Design
Asal Mehradfar, Xuzhe Zhao, Yue Niu +4
Analog and radio-frequency circuit design requires extensive exploration of both circuit topology and parameters to meet specific design criteria like power consumption and bandwid…
An Electronically Tunable 28-34 GHz 2-D Steerable Leaky Wave Antenna
Mahdi Alesheikh, Md Hedayatullah Maktoomi, Soheil Saadat +1
In this paper, a 2-D beam steering mm-wave antenna based on the leaky wave configuration is presented. Microstrip leaky wave antennas are known to exhibit beam rotation by changing…
Non-Linear Analog Processing in MIMO Systems with Coarse Quantization
Marian Temprana Alonso, Xuyang Liu, Hamidreza Aghasi +1
Analog to digital converters (ADCs) are a major contributor to the power consumption of multiple-input multiple-output (MIMO) receivers in large bandwidth millimeter-wave systems.…
Quantifying the Capacity Gains in Coarsely Quantized SISO Systems with Nonlinear Analog Operators
Farhad Shirani, Hamidreza Aghasi
The power consumption of high-speed, high-resolution analog to digital converters (ADCs) is a limiting factor in implementing large-bandwidth mm-wave communication systems. A mitig…
MIMO Systems with One-bit ADCs: Capacity Gains using Nonlinear Analog Operations
Farhad Shirani, Hamidreza Aghasi
Analog to Digital Converters (ADCs) are a major contributor to the energy consumption on the receiver side of millimeter-wave multiple-input multiple-output (MIMO) systems with lar…
Smart Detector Cell: A Scalable All-Spin Circuit for Low Power Non-Boolean Pattern Recognition
Hamidreza Aghasi, Rouhollah Mousavi Iraei, Azad Naeemi +1
We present a new circuit for non-Boolean recognition of binary images. Employing all-spin logic (ASL) devices, we design logic comparators and non-Boolean decision blocks for compa…
