This article presents an integrated power amplifier operating in the WR3.4 waveguide band between 220 and 325 GHz. The circuit is implemented in an 130nm BiCMOS technology, which offers heterojunction...
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...
