Low noise and low cost neural amplifiers

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
Extracellular neural signal acquisition requires low noise, high gain, low power, and low cost amplifiers. This paper presents amplifiers with a simple architecture that ensures a good compromise among these characteristics. We present three amplifiers based on the same architecture, in which the first stage is a differential pair, respectively based ...

Desensitized CMOS Low-Noise Amplifiers

IEEE Transactions on Circuits and Systems I: Regular Papers, 2008
The minimum attainable noise figure for scaled- CMOS low-noise amplifiers (LNAs) is limited by impedance mismatches such as the well-known noise/power tradeoff. In this paper, we show that a power-constrained optimization of the device noise resistance parameter, Rn, significantly reduces the impact of mismatches and variations and leads to an almost ...

A Low-Noise Amplifier

Proceedings of the IRE, 1948
This paper describes an amplifier circuit which yields very low noise factor, consisting of a grounded-cathode triode followed by a grounded-grid triode. The combination is entirely noncritical and provides the low noise factor of a triode with the high amplification and stability of a pentode.

MMSE matching for low noise amplifier

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
This paper presents a new theoretical framework for designing the minimum mean squared error (MMSE) matching network for a low noise amplifier (LNA). The MMSE matching network is determined by reformulating the matching problem as a continuous-time estimation problem and solving for the Wiener-Hopf equation.
