Abstract:For higher integration density, X-band power amplifiers (PAs) with CMOS technology have been widely discussed in recent publications. However, with reduced power supply voltage and device size, it is a great challenge to design a compact PA with high output power and power-added efficiency (PAE). In the proposed design, a 40-nm standard CMOS process is used for higher integration with other RF building blocks, compared with other CMOS PA designs with larger process node. Transistor cells are designed with neut… Show more
“…Ref. [15] showed a better EC performance, while our work had advantages in peak output power as well as wide-band performance. In addition, PA in this work occupied a smallest core-area among the listed ones, and the compactly designed TF networks contributed a lot.…”

“…Many of them were based on a high supply voltage (2.8~3.6 V), and only ref. [15,16] reported PAs operating on a lower power supply (1.0/1.2 V). The fabricated PA in this work exhibited higher EC (Psat/V 2 sup) performance than most of listed works.…”

“…Recently, researches on CMOS PA have been intensified. [11,12,13,14,15,16,17,18] The integration can be greatly improved via CMOS technology, and the power consumption as well as fabrication cost can be reduced simultaneously. However, the lower operating voltage of CMOS PA limits its output power.…”
CMOS power amplifier (PA) has advantages in power consumption and integration, while the lower operating voltage limits its output power. An area efficient power combiner needs to be designed to improve the output power of CMOS PA. An X-band integrated PA using 65-nm CMOS bulk technology was presented in this work. The whole PA consists of two differential stages: a one-way drive amplifier and a two-way main amplifier. By employing a compactly designed high-k output transformer, the CMOS PA occupied a small core-area of 0.47×0.57mm 2 , and delivered 21.6 dBm of measured saturated output power with 23.6% of power-added efficiency at 10 GHz from a 1.2-V power supply. Simultaneously, this PA can operate well in 8~15 GHz wideband. key words: silicon CMOS, power amplifier, RF integrated circuit, onchip transformer Classification: Integrated circuits This article has been accepted and published on J-STAGE in advance of copyediting.
