A CMOS LNA With an Integrated Direct-Conversion Mixer-Based Power Detector for Low-Power IoT Radio Applications 150 150
Author(s): Yunfan Gao, Minghan Liu, Mengting Yan, Cristian Cassella, Miriam Leeser, Marvin Onabajo

Abstract:

This letter presents a 2.8-GHz low-power CMOS low-noise amplifier (LNA) with an embedded self-mixing power detector (PD) for low-overhead RF power monitoring. The detector reuses two existing LNA node voltages as the signal and local oscillator (LO) inputs for direct downconversion mixing, which avoids a dedicated LO generator, coupler, or …

Abstract:

We present a 32-Gb/s/ $\lambda $ dense wavelength-division multiplexing (DWDM) bandpass-filtered clock-forwarding link with nine channels on a 200-GHz grid: eight for data and one for clock forwarding, intended for next-generation co-packaged optics (CPO). Using an injection-locked oscillation (ILO) technique for jitter filtering, the forwarded clock (FWDCLK) tracks most of …

Design and Analysis of Windmill-Shaping-Geometry Eight-Phase Oscillator Incorporating Magnetic and Dual-Injection Coupling Techniques

Design and Analysis of Windmill-Shaping-Geometry Eight-Phase Oscillator Incorporating Magnetic and Dual-Injection Coupling Techniques 150 150
Author(s): Ya Zhao, Runchen Wang, Lingao Huang, Haitao Ren, Jun Yin, Pui-In Mak, Li Geng, Chao Fan

Abstract:

This article reports a compact millimeter-wave (mm-wave) quad-core eight-phase oscillator featuring magnetic coupling and dual-injection coupling. Specifically, the quad-core oscillator is integrated in an LC-ring configuration via a windmill-shaping transformer for phase noise (PN) and chip area reduction. The eight-phase oscillator could eliminate the oscillation mode ambiguity and save the …

A 256-Channel Solid-State Nanopore Readout Array With 193-pA TIAs and Event Detection at 1-MHz in 65-nm CMOS

A 256-Channel Solid-State Nanopore Readout Array With 193-pA TIAs and Event Detection at 1-MHz in 65-nm CMOS 150 150
Author(s): Sander Crols, Filip Tavernier, Carolina Mora Lopez, Marian Verhelst, Nick Van Helleputte

Abstract:

Solid-state nanopore single-molecule sensing aims to replace the commercially available biological nanopores. Array sizes have remained limited due to the area and power consumption of the transimpedance amplifiers (TIAs), thus preventing throughput and cost scaling. This article presents a 256-channel readout array for solid-state nanopore single-molecule sensing in 65 nm CMOS. …

Integrated Low-Power Self-Coherent Kramers–Kronig Millimeter-Wave Receiver With Nonlinear Analog and Mixed-Signal Computing

Integrated Low-Power Self-Coherent Kramers–Kronig Millimeter-Wave Receiver With Nonlinear Analog and Mixed-Signal Computing 150 150
Author(s): Sherif Ghozzy, Muhamed Allam, Emir Ali Karahan, Zheng Liu, Kaushik Sengupta

Abstract:

A critical challenge in scaling up high-frequency wireless communication in the millimeter-Wave (mmWave) spectrum has been poor energy efficiency of the constituent transceivers, particularly on the highly energy constrained user equipment (UE). Receiving spectrally-efficient wireless signals (e.g., 64-quadrature amplitude modulation (QAM) etc.) require coherent transceivers with programmable frequency synthesizers, …

Abstract:

This article presents a calibration-free fractional-N cascaded phase-locked loop (PLL) employing a sampling phase detector (SPD)-bypass-based phase-domain oversampling noise-and-spur cancellation (P-OSNSC) technique. By incorporating an oversampling cancellation path that eliminates the gain errors and noise cancellation bandwidth limitation introduced by the SPD, the proposed architecture suppresses noise from the …
