Abstract
Self-heated JFets, suitable for use in low background focal planes cooled to cryogenic temperatures, have been developed and tested. For feedback resistances of 2 E 10 ohm at 4.2K the noise contributed by the amplifier is less than the Johnson noise of 2 μv/Hz1/2. Excellent dc stability has been demonstrated at a power level of 0.1 mw per JFet. These devices offer the possibility of much improved performance, greater reliability and less sensitivity to nuclear radiation when compared to MosFets.
