A low noise cascode amplifier

open access: yesJournal 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 ...
