We present the design, implementation, and experimental validation of a millimeter-wave (mmWave) integrated sensing and communication (ISAC) hardware testbed. Our contribution includes the algorithms ...
This paper proposes a low-power and self-interference-tolerant receiver for shared-aperture in-band full-duplex arrays. A transformer using an asymmetric center-tap configuration provides high common-...
In this paper, we present an investigation of a fully passive positioning system based on radiometric measurements. The proposed technology enables passive Direction-of-Arrival (DoA) estimation of hum...
This paper presents a spectrum-agile 60 GHz cognitive radio architecture that achieves a 94% reduction in idle power consumption via a hierarchical wake-up strategy. The system dynamically scales from...
This paper demonstrates a correlation-based RF front-end approach that leverages pump-modulated parametric frequency conversion to enable continuous-time, waveform-selective signal processing. By trea...
This paper presents the first demonstration of a W-band high-output-power direct digital RF transmitter using a Manchester (MAN)-encoded 1-bit band-pass delta-sigma modulator (BPDSM) and a frequency t...
This paper presents an E-band 2×2 unit phased array with stitching scalability from die-to-die up to reticle-to-reticle for wafer-scale phased-array systems, implemented in 28-nm CMOS technology. The ...
This paper presents a compact D-band time-division-duplex (TDD) front-end in 130-nm SiGe BiCMOS. The design features a novel, ultra-compact asymmetric T/R switch based on a reconfigurable tri-conducto...
This paper presents a 4-channel RF beamforming front-end in 40-nm bulk CMOS. Each channel integrates an active phase shifter (PS), a variable-gain amplifier (VGA), and a power amplifier (PA). Quadratu...
This paper presents the design, evaluation, and performance of two dual-channel radar monolithic microwave integrated circuits (MMICs), a transmitter and a receiver. Sophisticated chip layouts mitigat...
