Author(s): Mengru Yang, Dixian Zhao, Chenyu Xu, Peng Gu, Yongran Yi, Mohan Guo, Xiangxi Yan, Liangliang Liu, Yuan Chai, Huiqi Liu, Xiaohu You

Abstract:

This article presents K/Ka-band four-element four-beam phased-array transmitter (TX) and receiver (RX) front-ends. Hybrid-packaged technology is employed, consisting of one TX/RX 65-nm CMOS beamformer and four 0.1- $mu$ m GaAs power amplifiers (PAs)/low-noise amplifiers (LNAs). Each beam maintains a full connection to every antenna element without degrading …

A D-Band Wideband Single-Ended Neutralized Up-Conversion Mixer with Controlled LO Feedthrough in 65nm CMOS

A D-Band Wideband Single-Ended Neutralized Up-Conversion Mixer with Controlled LO Feedthrough in 65nm CMOS 150 150
Author(s): Chun Wang, Chenxin Liu, Hans Herdian, Abanob Shehata, Jill Mayeda, Kazuaki Kunihiro, Hiroyuki Sakai, Atsushi Shirane, Kenichi Okada

Abstract:

A D-band wideband passive single-ended up-conversion mixer with controlled LO feedthrough in 65nm CMOS process is presented in this letter. The LO feedthrough was controlled by the varactor and the neutralizing transmission line between the LO and RF ports of the mixer. In measurement, the proposed passive single-ended mixer had …

Monolithic Electronic–Biophotonic System-on-Chip for Label-Free Real-Time Molecular Sensing

Monolithic Electronic–Biophotonic System-on-Chip for Label-Free Real-Time Molecular Sensing 150 150
Author(s): Christos Adamopoulos, Hyeong-Seok Oh, Sidney Buchbinder, Panagiotis Zarkos, Pavan Bhargava, Asmaysinh Gharia, Ali M. Niknejad, Mekhail Anwar, Vladimir Stojanović

Abstract:

Label-free miniaturized optical sensors can have a tremendous impact on highly sensitive and scalable point-of-care (PoC) diagnostics by monitoring real-time molecular interactions without any labels. However, current biophotonic platforms are limited by complex optical and external readout equipment, precluding their use in a PoC setting. In this work, we address …

A Radiation-Hardened 15–22-GHz Frequency Synthesizer in 22-nm FinFET

A Radiation-Hardened 15–22-GHz Frequency Synthesizer in 22-nm FinFET 150 150
Author(s): David Dolt, Samuel Palermo

Abstract:

High-speed radiation-hardened frequency synthesizers are a key block in spaceborne communications systems. This article presents a 15–22-GHz radiation-hardened phase-locked loop (PLL) designed in a 22-nm FinFET process with hardening techniques for single-event upset (SEU) and total ionizing dose (TID) implemented in all key PLL blocks. Electrical performance tradeoffs arising from …

An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS

An IEEE 802.15.4/4z Coherent Quadrature Hybrid Correlation UWB Receiver in 65-nm CMOS 150 150
Author(s): Yunzhao Nie, Woogeun Rhee, Zhihua Wang

Abstract:

This article presents a coherent ultra-wideband (UWB) receiver architecture based on a quadrature hybrid correlation (QHC) method that significantly reduces the digital-correlation-relevant power in the conventional standard-compliant UWB receiver. The proposed QHC receiver front end employs analog correlation, two-step synchronization with a digital-assisted path, and time-interleaved (TI) sampling methods for …

Abstract:

We demonstrate a 3-D heterogeneously integrated dense wavelength-division multiplexing (DWDM) silicon-photonic transmitter simultaneously modulating eight 200-GHz spaced wavelengths at 50 Gbps/ $\lambda $ each, to deliver an aggregate per-fiber bandwidth of 400 Gbps. All necessary $O$ -band optical components are fully integrated on the photonic integrated circuit (PIC), including an eight-wavelength laser array, …
