Very low-noise, high-accuracy programmable voltage reference
نویسندگان
چکیده
We have designed and tested a very low-noise, highaccuracy programmable voltage reference that is intended as an alternative to batteries for the realization of automated low-frequency noise measurement systems. The output voltage, which can be set via a built-in RS232 interface, ranges from 0 to 5 V with a resolution and long-term stability of 250 V. The power spectral density of the output voltage fluctuations is less than 2 10 16 V/Hz at 100 mHz and remains below 10 17 V/Hz above 1 Hz.

متن کاملProgrammable, very low noise current source.
We propose a new approach for the realization of very low noise programmable current sources mainly intended for application in the field of low frequency noise measurements. The design is based on a low noise Junction Field Effect Transistor (JFET) acting as a high impedance current source and programmability is obtained by resorting to a low noise, programmable floating voltage source that al...
متن کاملHow to Reduce Reference Noise by Half - AN3531
A low-noise, 2.5V reference is constructed by stacking four 2.5V reference ICs in series. The resulting 10V output is divided back to 2.5V, and a low-noise unity-gain buffer added. This stacked-reference design reduces noise because the noise from each IC, being random and uncorrelated, partially cancels each other out. The low-frequency 1/f noise (LF noise) generated by a voltage reference at ...
متن کاملSection 7.1: Voltage References
Reference circuits and linear regulators actually have much in common. In fact, the latter could be functionally described as a reference circuit, but with greater current (or power) output. Accordingly, almost all of the specifications of the two circuit types have great commonality (even though the performance of references is usually tighter with regard to drift, accuracy, etc.). This sectio...
