| Popis: | With the emergence of the internet-of-things (IoT), many devices process data through the IEEE 802.11 wireless networks. To satisfy the increased data processing, the wireless fidelity (Wi-Fi) networks must have sufficient capacity. IEEE 802.11ax is formulated to provide higher data processing capabilities for IoT applications. The IEEE 802.11ax receiver operating at 5[Formula: see text]GHz must be able to withstand interference from nearby IoT applications. Hence, the low-noise amplifier (LNA) employed in such receivers must have a high input-referred third-order intercept point (IIP3). This paper aims to present a wideband LNA operating at 5[Formula: see text]GHz with high IIP3 for modern IoT transceivers using IEEE 802.11ax protocol. The LNA is designed and implemented in UMC 65[Formula: see text]nm CMOS technology using the Cadence virtuoso design tool. The proposed LNA can provide a maximum gain of 17.64[Formula: see text]dB while consuming 8.18[Formula: see text]mW of power from a 1.2[Formula: see text]V supply. It can be noted that the minimum noise figure (NF) achieved is 3.67[Formula: see text]dB and the corresponding IIP3 is 9.44[Formula: see text]dBm at 5[Formula: see text]GHz from the pre-layout simulations. |
