Linearization of subthreshold low-noise amplifiers
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013This paper presents a subthreshold cascode low-noise amplifier (LNA) with inductive source degeneration and third-order linearity enhancement. The LNA architecture includes an inductor and a capacitor at the gate of the cascode transistor for partial cancellation of third-order distortion components.

MHEMT G-band low-noise amplifiers
2013 IEEE MTT-S International Microwave Symposium Digest (MTT), 2013To improve the performance of G-band equipment for humidity sounding of the atmosphere, a high-gain and low-noise amplifier is needed. Here we describe and report the performance of several low-noise amplifier microchips intended for 183-GHz water vapor profiling application.

Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.

Low-noise amplifier for myoelectric measurements
Medical & Biological Engineering, 1973At least two conclusions may be drawn from our experiences: (a) whereas manual analysis necessarily oversimplifies the picture of a circuit's operation, it is still a useful guide. (b) f.e.t.s. are a practical answer to the high-value, unbalanced source impedances and low signal levels found in biological phenomena.

Transistors as low-noise amplifiers
Proceedings of the IEE - Part B: Electronic and Communication Engineering, 1959The noise properties of a transistor considered as a circuit element (physical origins of noise are not discussed) are outlined, and an equivalent circuit containing two correlated noise generators is described. A method of measuring the magnitudes of the two generators and their correlation coefficient is given, and the results of measurements of ...

A low noise instrumentation amplifier
Journal of Physics E: Scientific Instruments, 1974Difficulty in obtaining very low noise difference amplification with gain stability using conventional operational amplifier circuitry is considered. A design procedure eliminating the incompatibility of gain stability and low noise is discussed. The design, circuit details and performance of low noise, high input impedance amplifier with good gain ...

ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 2002
In this paper two Low-Noise Amplifiers (LNA) are presented. The first topology is a two-stage LNA that is ac coupled to the mixer, while the second one is a single stage LNA that can be dc coupled to the mixer. These circuits have small sensitivity to temperature variations and special biasing techniques allow us to reduce the effects of the process ...

Analysis of Low-Noise Amplifier
2021 6th International Conference on Intelligent Computing and Signal Processing (ICSP), 2021Low-noise amplifiers (LNAs) are some of the simplest yet the most essential devices in the field of engineering. In its most basic sense, an LNA is an electronic device that boosts a lower-power signal to a sufficient level without creating significant disruption in the circuit's signal-to-noise ratio.

A superior low-noise amplifier
1970 IEEE International Solid-State Circuits Conference. Digest of Technical Papers, 1970A circuit consisting of a Darlington pair of transistors and a dc source connected to the emitter of the input transistor, found to offer a significant improvement in noise performance at low frequencies, will be described.

Abstract The usefulness of a low-noise amplifier depends upon the noise environment in which it is used, and upon the way in which it is used. Noise received by the aerial originates in extraterrestrial sources, in the atmosphere, and from the ground.
