A 10mW Bluetooth Low-Energy Transceiver with On-Chip Matching

📋 论文概要

本文提出一款功耗仅10mW的蓝牙低功耗收发器，集成了片上匹配网络，解决了无线传感器节点在低功耗、抗干扰和小尺寸之间的权衡问题。通过采用LO运行在接收频率以下或等于接收频率的架构，降低了LO生成和分布的功耗。

💡 主要创新点

• 实现10mW超低功耗的蓝牙低功耗收发器，显著降低系统功耗。
• 集成片上匹配网络，减少外部元件，缩小应用尺寸并简化设计。
• 采用创新的LO架构，在接收和发射模式下优化频率规划，提升能效。

Rahul Todi, William Aartsen, Wim Kruiskamp, Johan Haanstra, Enno Opbroek, Søren Rievers, Peter Seesink, Harrie Woering, Chris Smit Dialog Semiconductor, 's-Hertogenbosch, The Netherlands Wireless sensor nodes present a difficult compromise at the system level between low power consumption, interference resilience and ease/size of the application. Recent low-power designs employ receiver architectures in which the LO runs at or below the received frequency (in TX at the required RF frequency). These architectures facilitate LO generation and distribution at a favorably low frequency, but cause a systematic, hard-to-circumvent susceptibility to out-of-band blockers in RX [1] and pulling in TX [1,2]. The presented Bluetooth Low-Energy (BLE) transceiver, as shown in Fig. 13.3.1, was purposely designed with a classic double-frequency VCO architecture to avoid these inherent weaknesses, but still significantly reduces the power
