This paper reviews and analyzes four reported low noise amplifier (LNA) design techniques applied to the cascode topology based on CMOS technology: classical noise matching (CNM), simultaneous noise and input matching (SNIM), powerconstrained noise optimization (PCNO), and power-constrained simultaneous noise and input matching (PCSNIM) techniques. Very simple and insightful sets of noise param...

In this paper, a CMOS Multi-band LNA using High-Q active inductors load with a binary code band selector suitable for multi-standards wireless applications is proposed. Using an improved high-Q active inductor including two bits binary controlled code, the multi-band low noise amplifier operating at four different frequency bands is realized. The proposed amplifier is designed in TSMC 0.18-um C...

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 analyzed for C-band for recent process technologies available for CMOS and BiCMOS for IEEE 802.11 b/g.

Tower mounted amplifiers (TMA) serve to lower the system noise figure (NF) in cellular base-stations. For performance reasons, the TMA is located as near to the receiving aerial as practical and has to be connected to the rest of the radio at the tower’s base by a long run of coaxial cable. The parameters critical to TMA performance are low NF for reasons of optimizing coverage area, high gain ...

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...
