This work presents a mixer-first zero-IF pulsed-LO beam-steering receiver operating at 2.4 GHz. The receiver leverages a pulsed LO delay-locked to an external reference (XO). The delay-chain and pulse...
This paper presents a multi-source-collaborative reconfigurable RF energy harvesting (MSCR-RFEH) interface IC that can efficiently harvest and combine the energy from four RF sources. The proposed int...
A high resolution active true time delay (ATTD) with quasi-quadrature (QQ) generator for RF self-interference cancellation (SIC) for full-duplex (FD) system is presented. Unlike conventional RF SICs b...
This paper presents a miniature localization tag for LEO satellite localization using algorithm-hardware co-design. On the algorithm side, we achieve 10 dB reduction in required EIRP while maintaining...
This paper focuses on two complementary stacked bipolar power amplifiers (PAs): two-transistor stack and four-transistor stack. Based on the advanced 130-nm SiGe BiCMOS process, a comprehensive compar...
This paper presents a frequency reconfigurable dual-band load-insensitive transmit/receive (T/R) front-end (FE). The proposed T/R FE chip is composed of a frequency reconfigurable dual-band load-insen...
This paper presents an octave-bandwidth millimeter-wave local oscillator (LO) generator architecture covering a frequency range from 47 to 100 GHz. The proposed LO generator comprises six oscillator-e...
This paper presents a blocker-tolerant K-band low-noise amplifier (LNA) in a 55-nm SOI CMOS process. A gain-flattening notch amplification unit is proposed to simultaneously enhance interference immun...
To address electromagnetic circuit interaction challenges in passive networks of RF/mm-wave integrated circuits (ICs), this paper proposes a fully automated schematic-layout co-optimization framework....
Testing of millimeter-wave integrated circuits become increasingly challenging as operating frequencies and channel counts continue to scale, leading to high test cost and long measurement time. This ...
