A Review on Classification and Performance Analysis of Wideband Low Noise Amplifier

For a variety of uses at various frequency bands, severlrst stages CG sa wireless communication standards have been created, including Bluetooth, LongTermEvolution (LTE), Digital-Enhanced Cordless Telecommunications (DECTs), Wireless Fidelity (Wi-Fi), and the GlobalSystem for MobileCommunications (GSM). Receivers that handle several standards on a single chip are attractive because they allow varied applications to be accommodated in a single device. One method of realizing those receivers is to integrate many narrowband front-ends together. LNAs are a unique kind of electronic amplifier and the first active building block that are employed in communication systems to amplify extremely weak signals that are picked up by a receiver antenna. The received-signal is usually amplified by an LNA after being filtered by BPF. It is an essential part of the receiver since its parameters, including its gain, bandwidth, and noise Fig (NF), have an immediate impact on the data rate, dynamic range, and sensitivity of the system. The source degeneration LNA has appealing features like decent gain, low NF, and good input matching. The intended frequency range determines which transistor (MOS) the LNA should use. A well-designed DC bias strategy seeks to pinpoint the optimal quiescent point. While an active bias network is often preferred for addressing small to moderate temperature fluctuations, a resistor bias network can also yield satisfactory outcomes.Several approaches to wideband design include common gate stages, distributed amplifiers, and traditional LNA noise cancellation. Another workable approach to wideband LNA design is the resistive shunt feedback architecture, which combines feed-forward and feedback approaches. This makes an inductor-less LNA an appealing option
