چکیده

In this paper, we present the low noise amplifier using new feedback connection configurations. The UWB LNA is design in 0.18 m TSMC CMOS technique to achieve high gain, small size and low noise. The LNA achieved 11 dB of average power gain, low 2.87 dB noise figure (NF), -10.9 dB input match, -7 dB return loss, -3 dBm of IIP3 and only 0.54 mm size with 15 mW power consumption.

A Broadband Low Power CMOS LNA for 3.1–10.6 GHz UWB Receivers

A new approach for designing an ultra wideband (UWB) CMOS low noise amplifier (LNA) is presented. The aim of this design is to achieve a low noise figure, reasonable power gain and low power consumption in 3.1-10.6 GHz. Also, the figure of merit (FOM) is significantly improved at 180nm technology compared to the other state-of-the-art designs. Improved π-network and T-network are used to obt...

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...

A novel configuration for UWB LNA suitable for low-power and low-voltage applications

Two UWB LNAs based on a new configuration suitable for low-power and low-voltage applications are presented. The proposed configuration saves bias circuit because of sharing only a bias circuit. In designing LNA-1 good phase linearity property achievement is followed for low-power and low-voltage applications, while in LNA-2 the main concerns are high power gain, by keeping low-power consumptio...

Design of an Inductor-Less LNA Using Resistive Feedback Topology for UWB Applications

Low Noise Amplifier (LNA) is one of the essential components in Ultra Wideband (UWB) devices. Conventional LNA suffers from large chip area, high power consumption and inadequate Noise Figure (NF). A compact UWB LNA in the bandwidth of 3.1 to 10.6 GHz is proposed. The design is based on inductor-less configuration using the resistive shunt feedback topology and noise canceling techniques for wi...

A Highly LinearLNA with Noise Cancellation for 5.8–10.6 GHz UWB Receivers

This paper presents a new ultra-wideband LNA which employs the complementary derivative superposition method in noise cancellation structure. A pMOS transistor in weak inversion region is employed for simultaneous second- and third-order distortion cancellation. Source-degeneration technique and two shunt inductors are added to improve the performance at high frequencies. The degeneration induc...
