A Reconfigurable Intelligent Surface (RIS) can help establish a secondary Line of Sight (LOS) to maintain the communication link when a blockage occurs in the direct path between the transmitter and r...
This paper presents an ultra-wideband integrated phased-array beamformer chip integrating 4 transmit/receive (TRX) channels in 65-nm CMOS process. Each channel features 16.2 dB TX gain over a 12:1 3-d...
This work presents a 16-phase delay-locked loop operating across 8 to 28 GHz in 28 nm CMOS. The proposed two-stage nested-feedback architecture enables the DLL to overcome the frequency limit set by t...
For accurate probing up to sub-THz frequencies, on-wafer calibration is critical. However, most Impedance Standard Substrates (ISSs) used in calibration are made of alumina, even though most MMICs are...
