Abstract

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 variety of uses requiring low noise gain in the 1 Hz to 30 MHz frequency range.
