Low Noise Amplifiers (LNAs) amplify weak signals received by the antenna in communication systems. Every wireless system module typically consists of one or several LNAs. Applications include GPS receivers, wireless data systems, satellite communication, cellular handsets, radio systems, etc. The low noise in the receive chain is reduced by the gain of the LNA and therefore its function is prim...

As a design study for the LHC experiments a 'Low Noise Amplifier Shaper' for capacitive detectors is developed. This amplifier is designed in 0.6 um CMOS technology from AMS. The goal was to design an amplifier with a noise contribution of 250 electrons, and 12 electrons per pF contribution from the input capacitor and a relative high gain. A test chip with two versions of the amplifier, a 'rad...

This paper describes a 1.9 GHz, 25 mW , 0.25 μm CMOS Low Noise Amplifier (LNA), intended for use in a DECT (Digital Enhanced Cordless Communications) Receiver. The LNA has been simulated with Cadence Spectre and the results show that it provides a gain of more than 15 dB, for a noise figure of 2dB, and an input referred IP3 of −5dBm. We present the LNA architecture and the circuit analysis alon...

A 2.4-GHz single-stage CMOS low noise amplifier (LNA) structure with ultra low power consumption is proposed. A current reuse technique is used to decrease power dissipation with increasing amplifier transconductance for the LNA. Thus, the same amplifier transconductance for the LNA will be achieved at decreased power dissipation. Also, due to the use of an inverter-type amplifier which has a s...

Low noise amplifier when simulated for system level configuration, the scattering matrix in general and scattering parameters in specific play vital role in performance of low noise amplifier for various frequency bands. In this paper the scattering parameter performance was analysed for S-band for recent process technologies available for CMOS and BiCMOS for IEEE 802.11 b/g.

The signal conditioning circuit of the electrostatic sensor is a small signal amplifier that collects and amplifies the detected electrostatic noise. Due to its high amplification properties, the output signal is highly susceptible to be defaced by intrinsic or extrinsic noise. This paper is proposed a low noise signal conditioning circuit for electrostatic sensor. A circuit model is proposed a...

Two kinds of low noise amplifier (LNA) for single-end cascade structure and differential cascade structure respectively are presented in this paper. Cadence software is used to optimize the two circuits. It provides a series of good results in N...

This paper presents a ultra wideband low noise amplifier for 6GHz Applications. This proposed LNA is the extension of inductively common source amplifier and in this design we used transistor multifingering techniques in order to reduce noise and improves gain. This LNA is simulated by using UMC .18um CMOS mixed signal/RF process in cadence virtuoso. In this design, used current source biasing,...
