“…The LNA achieves a peak gain of 9.94 dB and minimum NF of 1.086 dB in Mode-I. The proposed LNA provides the best noise performance when compared with the LNAs reported in [22][23][24][25][26][27][28][29][30][31][32][33][34][36][37][38][39][40][41][42][43][44][45][46][47]. The linearity performance of the LNA is characterized using a two-tone test.…”

“…The common-gate (CG) based LNAs, and resistive load based LNAs are also ideal candidates for wideband LNA designs. Some of the recently proposed UWB LNA designs are reported in [17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Cross-coupled and body driven techniques are exploited in [17], for operating at a reduced supply voltage, current reuse and forward body bias techniques are used in [18].…”

“…Dual-resonance network for UWB applications is proposed in [23,24], a two-stage LNA with resistive feedback and on-chip inductors for frequency response improvements is employed. An LNA with double g m -boosting and positive feedback is reported in [25], and an LNA with built-in self-test (BIST) for strong immunity to interferers is reported in [26]. Noise-cancelling LNA topologies with current reuse techniques is reported in [27,28].…”

“…Recently, in [29], peaking inductors between the stages of the cascade LNA is used for wideband performance, and in [30] linearity improvement for UWB LNA with post-distortion technique is proposed. The high voltage gains reported in [25][26][27][28] will cause dynamic range reduction due to blocker effect, and the receiver output will be distorted resulting in lossy demodulation.…”

The wireless communication in the next generation is bound to be driven by massive machine-type communication or in other words Internet-of-things (IoT). In the near future, the need for effective communication and higher data processing rates will require IoT devices to support 5G networks. For 5G IoT applications in the ultra-wideband range (3.1-10.6 GHz), the analog receivers must provide both high-performance and energy efficiency simultaneously. This work addresses the demands of 5G IoT analog receivers by proposing an ultra-low-power low noise amplifier (LNA) employing cross-coupled positive shunt feedback. The proposed LNA is designed in UMC 180 nm deep n-well process, and the post-layout characterization is done using Cadence SpectreRF. The proposed design achieves a peak gain of 9.94 dB and a noise figure of 3.2-1.086 dB along the usable bandwidth of 3.2-9.625 GHz while consuming an ultra-low-power of 493 µW from a 1-V power supply. The maximum input-referred third-order intercept point of 8.81 dBm is attained for an input signal at 2.4 GHz and the interferer as close as 2.425 GHz. The LNA consumes a minimal layout area of only 676.2 µm × 350.7 µm. The proposed LNA has the better figure-of-merit while consuming almost 50% less power than the recently reported sub-mW LNA in literature.
