Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
Low Noise x1000 Amplifier
Here’s the specs: Voltage noise 2.5nV/√Hz, Gain 1000, bandwidth 0.3Hz to 500kHz.
Frequency Compensated Attenuator Tests Amplifiers
We’re working on a low-noise amplifier product, and to test it we need some attenuation, to generate clean low-level signals. The pdf shows a schematic and describes some test results.
Weight gain at NIST
We like to measure things – and NIST is our source of the best measurement advice.
Low Noise, Low Drift Techniques
This presentation has a set of clear, well thought out images describing how chopper techniques can reduce 1/f noise, reduce drift, and even how to cancel the nasty charge injection of FET switches.
Quantization Noise
We notice the assertion that A/D converter quantization noise is equal to ADU/SQRT(12), where ADU is the quantization unit or LSB.
Low Noise NMR Design
Careful consideration of all the elements of a system’s design can lead you to some very improved performance.
