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 …

A Battery-Free BLE Backscatter Communication Chip for Wearable Systems

A Battery-Free BLE Backscatter Communication Chip for Wearable Systems 150 150
Author(s): Yongling Zhang, Ji Xiong, Junzai Chen, Xiaoyu Li, Jinrui Zuo, Yan Wang, Xiaoyi Wang, Miao Meng

Abstract:

This letter presents a backscatter chip that features bidirectional communication with commodity bluetooth low-energy (BLE) transceivers. For uplink, the chip reflects a reverse-whitened BLE tone into single-sideband (SSB) GFSK-modulated BLE packets via a proposed replica VCO-based GFSK modulator and an inductor-free SSB reflector. For downlink, the BLE packets are frequency …
