Multi-antenna wireless communication improves spectral efficiency by reusing frequencies at different locations in space using beamforming and spatial multiplexing. In the past, research has extensively focused on dynamically reusing unused frequency

Implementing flexible, software-defined duplexing transceivers remains challenging due to the inherent self-interference from TX to RX that requires cancellation in the RF/analog domain. Previously, we presented a novel, duplexing, integrated, single

We present a hardware accelerator, fabricated in 180 nm CMOS, for baseband timing of BLE mesh networks. The timing circuitry augments the BLE physical layer with a new command that enables scalable synchronization and aggressive duty-cycling of mesh

We present a tunable LNA for software defined radio based on a compact, tunable transmission line (CTTL) element. The CTTL acts as a passive, widely tunable LC resonance in a cascoded, common source LNA to implement an instantaneously narrowband, mul

This article introduces a circuits model for a proposed spin-based device called a spin–orbit torque field-effect transistor (SOTFET) that can operate as a nonvolatile memory and logic device. The SOTFET utilizes an FET structure with a ferromagnet

The adoption of 5G standards requires new wireless devices to support not only traditional RF bands, but also mmW frequencies up to and beyond 40GHz. Such mmW hardware typically requires narrowband LC resonant circuits for efficient, low-noise operat

Vector accelerators can efficiently execute regular data-parallel workloads, but they require expensive multi-ported register files to feed large vector ALUs. Recent work on in-situ processing-in-SRAM shows promise in enabling area-efficient vector a
