This paper presents the design scheme of an ultra-broadband compact mm-wave Butler Matrix. The design employs new transformer-based swapped-port couplers and lumped LC-based π-network phase shifters to achieve an extremely compact chip size and ultra-broad bandwidth. This scheme is implemented as a 4×4 Butler Matrix in a standard 65nm CMOS(More)
This paper presents a multi-phase sub-harmonic injection locking technique to significantly extend the locking range of a multi-phase injection locking oscillator (ILO). Leveraging this technique, a scalable and cascadable “active frequency multiplier” chain architecture is proposed, which achieves THz signal generation from a low mm-wave(More)
In this paper, we present a fully integrated multi-modality CMOS cellular sensor array with four sensing modalities to characterize different cell physiological responses, including extracellular voltage recording, cellular impedance mapping, optical detection with shadow imaging and bioluminescence sensing, and thermal monitoring. The sensor array consists(More)
