A CMOS LNA With an Integrated Direct-Conversion Mixer-Based Power Detector for Low-Power IoT Radio Applications

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 …

Analysis and Design of a 2–8 GHz Eight-Phase N-Path Passive Mixer-First Receiver With Overlapping LO Signals and Harmonic Loss Suppression

Analysis and Design of a 2–8 GHz Eight-Phase N-Path Passive Mixer-First Receiver With Overlapping LO Signals and Harmonic Loss Suppression 150 150
Author(s): Shimin Huang, Sanaz Sadeghi, Alyosha C. Molnar

Abstract:

This article presents a technique for suppressing the effects of overlapping LO signals in an eight-phase N-path passive mixer-first receiver. In particular, an architecture for an eight-phase mixer is presented, allowing the receiver to operate at higher frequencies with overlapping 25% duty-cycle LO pulses without incurring significant degradation in loss or …

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation

A Low-Power 10Mbps Squaring-First UWB Receiver Using Frequency Hopping and Two-Tone Modulation 150 150
Author(s): Lexie Drackley, Aman Gupta, David D. Wentzloff

Abstract:

This paper presents a low-power 10Mbps squaring-first ultra-wideband (UWB) receiver using frequency hopping code-division multiple-access (FH-CDMA) and two-tone OOK modulation for wireless personal area networks (WPAN). The two-tone receiver architecture preserves IF filtering, improves resilience to narrowband interference, and saves power by eliminating the RF local oscillator. FH is applied …

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, …
