Abstract

This paper presents the system and circuit level design of a NB-IoT receiver (RX) based on 3GPP Technical Specification (TS) 36.101. This design targets serving many NB-IoT operation bands, so no off-chip filter is used. This dictates large linearity specification on the RF front end to avoid desensitization by −15dBm out-of-band blockers (OOBs). Large linearity specification leads to large power consumption. A solution is proposed to reduce power consumption of the RF front end, while achieving high gain and high linearity. The proposed RF front end provides 29.5dB gain and −10.9dBm IIP3 while consuming 2mW from a single 1.1V power supply. The solution includes adding gain programmability to conventional resistive feedback LNA to relax the trade-off between linearity and power consumption. The RF front end is designed using a 40nm CMOS technology and occupies an area of 0.2mm2.
低功耗0.4-2.3GHz NB-IoT UE接收机,具有- 15dBm耐oob射频前端
本文介绍了一种基于3GPP技术规范(TS) 36.101的NB-IoT接收机(RX)的系统和电路级设计。本设计的目标是服务多个NB-IoT操作频段,因此不使用片外滤波器。这决定了RF前端的大线性规格,以避免- 15dBm带外阻滞剂(oob)的脱敏。线性度规格大导致功耗大。提出了一种降低射频前端功耗,同时实现高增益和高线性度的解决方案。所提出的射频前端提供29.5dB增益和- 10.9dBm IIP3,同时从单个1.1V电源消耗2mW。该解决方案包括在传统的电阻反馈LNA中增加增益可编程性,以减轻线性度和功耗之间的权衡。射频前端采用40nm CMOS技术设计,占地面积为0.2mm2。
