This paper presents a continuously tunable delay line based on coupled transmission-line resonators whose resonant frequencies and coupling coefficients are controlled using BST (Barium Strontium Tita...
This paper presents a novel integrated, frequency-tunable SiGe active isolator. Its high isolation and linearity make it well-suited for communications circuits and other systems that require frequenc...
In this paper, a full duplex (FD) filtering antenna with nonreciprocal transmission characteristic, implemented by substrate integrated waveguide (SIW) integrated with the spatiotemporal modulation (S...
This paper presents detailed analysis and design of frequency tunable, all-port reflectionless nonreciprocal bandpass filter (NR-BPF) based on spatiotemporal modulation. All-port reflectionless NR-BPF...
In this keynote, we explore a fundamentally different paradigm — quantum-enabled matrix equation solvers — and their transformative potential for microwave and RF engineering.
Building on recent advan...
Superconducting Quantum Interference Devices (SQUIDs) exhibit exceptional magnetic flux sensitivity due to superconducting phase interference enforced by flux quantization in a closed loop of Josephso...
SQUID-based parametric amplifiers offer high gain, quantum-limited added noise, and wide tunability across the GHz spectrum. In this work, we present a full-circuit modeling of flux-pumped SQUID ampli...
This paper presents a physics-based temperature-dependent scalable 2-π equivalent circuit model of spiral inductors for cryo-CMOS circuit design. A physics-based modeling method is proposed to include...
This work investigates the suitability of an embedded wafer-level ball grid array (eWLB) package for cryogenic applications e.g., quantum computer, quantum sensing and radio astronomy. A 12GHz power a...
This paper evaluates a reflective type phase shifter (RTPS) qubit control. First, the precision limits of the RTPS at room temperature are investigated, achieving a record low 0.01° root-mean-square e...
