A 22.9–38.2-GHz Dual-Path Noise-Canceling LNA With 2.65–4.62-dB NF in 28-nm CMOS

Abstract

In this article, a 22.9-38.2-GHz dual-path noisecanceling low noise amplifier (LNA) is proposed, which can achieve a low noise figure (NF) by reducing the noise of both paths. Such LNA consists of one common gate (CG) amplifier with one three-stage transformer, one resistive feedback common-source (CS) amplifier, and two amplitude-adjusting amplifiers. The three-stage transformer is used in the CG amplifier to provide gain-boosting, noise-reducing, and wideband inter-stage matching operation, simultaneously. Meanwhile, amplitude-adjusting amplifiers with reconfigurable phase-tuning lines are utilized in both paths to optimize the noise-canceling performance. To verify the aforementioned principle, a dualpath noise-canceling LNA is implemented and fabricated using a conventional 28-nm CMOS technology. The proposed LNA consumed 18.9 mW under a 0.9-V supply. The measured NF is 2.65-4.62 dB within the operating frequency range of 22.9-38.2 GHz, while the peak gain is 14.5 dB. The in-band input 1-dB compression point (IP 1 dB ) and input third-order intercept point (IIP3) are −13.2 to −6.6 and −3.6 to 3.2 dBm, respectively.

“…SiGe LNAs present an NF in the 2-3-dB range in the Ka-/Ku-bands, with gains that span the 15-30-dB range [131], [132], [133], [134], [135], [136], [137], [138]. Sibased LNAs present more modest gain levels in the 12-20-dB range but show NFs close to those of GaAs (i.e., nearly 1 dB) up to 3.5 dB [130], [139], [140], [141], [142], [143], [144], [145].…”

“…Such inphase noise is generated from the source noise of M 1 , which is amplified by the auxiliary path before canceling. By properly adjusting the gains of M 3 and M 4 , the noise-canceling ratio is improved [48]. In the proposed NCLNA, the gain and operation bandwidth is determined by the performance of the main path.…”

“…The models in Section 4.3 are now used to develop a measure of link rate coverage for OtI scenarios with "traditional" or Low-e glass. Table 5 defines typical parameters for the 28 GHz BS and UE representative of recent advances in state-of-the art mmWave hardware [43][44][45][46][47]. We select conservative values for these parameters to reduce the possibility of overestimating data rates, and we include an additional 5 dB of losses in 𝑁 𝐹 .…”
