Abstract

To support increased device functionality and higher data-rates in LTE-enabled systems, while improving user experience and usage time, there is a need to reduce RFIC size and power consumption without degrading performance, while maintaining backward compatibility with legacy 2G/3G systems [1]. This paper introduces a 13mm2, 40nm CMOS 2G/HSPA+/TDSCDMA/UE cat. 4 transceiver that consumes 36/65mA battery-referenced current in 3G/LTE20 modes (B1, -50dBm TX, -60dBm RX). This is achieved in part by employing a multiport single-core LNA with a multitap inductor and a current-mode-driven single-core transmit mixer. Baseband-assisted calibration techniques help achieve <;1.2% RX EVM in LTE20 and >60dBm IIP2 in all bands. To save on platform area and cost, the RFIC supports single-ended LNAs, 32kHz clock generation, and free-running XTAL operation. TX SAW filters are not required.

9.1一个13mm2 40nm多频段GSM/EDGE/HSPA+/TDSCDMA/LTE收发器

为了在支持lte的系统中支持增加的设备功能和更高的数据速率，同时改善用户体验和使用时间，需要在不降低性能的情况下减小RFIC尺寸和功耗，同时保持与传统2G/3G系统的向后兼容性[1]。本文介绍了一种13mm2, 40nm的CMOS 2G/HSPA+/TDSCDMA/UE猫。4收发器，在3G/LTE20模式(B1， -50dBm TX， -60dBm RX)下消耗36/65mA电池参考电流。这部分是通过采用带有多抽头电感和电流模式驱动的单核传输混频器的多端口单核LNA来实现的。基带辅助校准技术有助于在所有频段实现60dBm IIP2。为了节省平台面积和成本，RFIC支持单端lna, 32kHz时钟生成和自由运行的XTAL操作。不需要TX SAW滤波器。
