摘要：
下一代（5G/6G）无线系统需要低功耗毫米波相控阵集成电路。可变增益低噪声放大器（VGLNA，Variable-gain LNAs）是降低硬件复杂度、提升性能并扩展功能的关键构建模块。本文针对两款用于相控阵集成电路的低功耗30GHz VG-LNA开展性能基准测试，两款器件可为30GHz 8×8天线阵列中18dB泰勒锥度提供7.5dB的增益控制，旨在全面验证这类新型VGLNA及其设计方法。具体而言，本文报道了第二款实现方案（VG-LNA2），相较于采用6个增益控制背栅电压和常规阈值电压MOSFET的首款实现方案（VG-LNA1），VG-LNA2采用更少的（4个）增益控制背栅电压以及超低阈值电压MOSFET，二者均基于相同的22nm FDSOI CMOS工艺制造。结果表明，VG-LNA2的性能与VG-LNA1相当，且功耗略低。总体而言，性能基准测试显示，这类新型VGLNA采用的设计方法可实现创纪录的低功耗和小尺寸方案，且能达到目标性能，不受增益控制背栅电压排布和晶体管组的影响，从而全面验证了该创新设计特性和有效设计方法的可行性。
英文摘要：
Next-generation (5G/6G) wireless systems demand low-power mm-wave phased-array ICs. Variable-gain LNAs (VGLNAs) are key building blocks enabling hardware complexity reduction, performance enhancement and functionality extension. This paper reports a performance benchmarking of two low-power 30GHz VG-LNAs for phased-array ICs, which provide a 7.5dB gain control for 18dB Taylor taper in a 30GHz 8x8 antenna array, for a comprehensive validation of the new class of VGLNAs and its design methodology. In particular, this paper reports a second and implementation (VG-LNA2) with a reduced number (four) of gain-control back-gate voltages and super-low-Vt MOSFETs, with respect to the previous first implementation (VG-LNA1) with six gain-control back-gate voltages and regular- Vt MOSFETs, both in the same 22nm FDSOI CMOS technology. The results show that VG-LNA2 exhibits performance comparable to those of VG-LNA1, with a slightly lower power consumption. Overall, the performance benchmarking shows that the design methodology adopted for the new class of VG-LNAs leads to record low-power consumption and small form factor solutions reaching the targeted performances, regardless of the arrangements of the back-gate voltages for gain control and transistor sets, resulting in a comprehensive validation of the innovative design features and effective design methodology.
