Appraisal of a low noise electrocardiogram
Journal of the American College of Cardiology, 1983 Two low noise electrocardiographic systems were designed to record low amplitude His-Purkinje potentials in the PR segment and delayed depolarization potentials in the ST-T segment from the body surface on a beat to beat basis. In one system, a bipolar electrode was utilized and the noise level was optimally reduced to 2 to 2.5 microV by a combination ...

Down With Noise: An Introduction to a Low-Noise Amplifier Survey
IEEE Solid-State Circuits Magazine, 2020 Numerous different circuits are created around the world on a daily basis, making it rather difficult for circuit designers to stay abreast of the latest developments. In an attempt to keep up with these new developments, researchers have compiled a number of spreadsheets that capture key designs and their features.

Low-Noise Techniques in Detectors [PDF]
Annual Review of Nuclear and Particle Science, 1988 We concentrate in this review on the fundamentals of low-noise techniques and on understanding the limits in the charge signal measurements. Charge collection and signal formation in detectors, the origin and properties of noise, noise and amplification of charge, and detectors and signal processing are discussed. (AIP)

Temporal Noise Analysis of Charge-Domain Sampling Readout Circuits for CMOS Image Sensors
Sensors, 2018 This paper presents a temporal noise analysis of charge-domain sampling readout circuits for Complementary Metal-Oxide Semiconductor (CMOS) image sensors. In order to address the trade-off between the low input-referred noise and high dynamic range, a Gm-

Journal of Research of the National Bureau of Standards, 1987 We describe the design, schematics, and performance of a very low noise FET cascode input amplifier. This amplifier has noise performance of less than [Formula: see text] and 0.25 [Formula: see text] over the 500 Hz to 50 kHz frequency range. The amplifier is presently being used in conjunction with a Penning ion trap but is applicable to a wide ...

Noise thermometry at ultra-low temperatures [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013 The options for primary thermometry at ultra-low temperatures are rather limited. In practice, most laboratories are using 195 Pt NMR thermometers in the microkelvin range. In recent years, current sensing direct current superconducting quantum interference devices (DC-SQUIDs) have enabled ...
