A variable-gain low-noise amplifier (LNA) suitable for low-voltage and low‐power operation
is designed and implemented in a standard 0.18 µm CMOS technology. With a current …

Low noise amplifier is the front end block of radio-frequency receiver system. Its design
required various characteristics such as power gain, noise figure, insertion losses and …

A 20-GHz low-noise amplifier (LNA) with an active balun fabricated in a 0.25-/spl mu/m SiGe
BICMOS (f/sub t/= 47 GHz) technology was presented by the authors in 2004. The LNA …

In software defined radio, the same radio front end is used to accommodate different
wireless standards operating in different frequency bands. The use of wideband or …

A dual gain low noise amplifier for a 5.6 GHz ISM band direct conversion receiver, has been
designed using a TSMC 0.25/spl mu/m CMOS process and features a gain controllable on …

A variable gain LNA with large and continuous gain variation is proposed. By adding a
simple gain-control loop at the second stage of a cascade LNA, a continuous gain tuning …

This paper presents a low‐noise and high‐linearity LNA based on InGaP/GaAs HBT for 5.3‐
GHz WLAN. Previous LNAs based on FET series (such as HEMTs) show excellent noise …

In the paper we present a 5.7 GHz gain-variable LNA. This LNA is designed in TSMC CMOS
0.18-μm technology based on an improved current-reused cascade common source …

In this work, a low-power single-ended-to-differential low-noise amplifier (LNA) is reported.
The circuit has been designed and optimized to be included in an IEEE 802.15. 4 standard …
