Constant and switched bias low frequency noise in p-MOSFETs with varying gate oxide thickness [PDF]

, 2002
The low-frequency noise power spectral density of MOSFETs is decreased if the MOSFETs are periodically switched 'off' (switched bias conditions). The influence of the gate oxide thickness on fixed bias and switched biased low frequency drain current ...

On the angular dependence of InP high electron mobility transistors for cryogenic low noise amplifiers in a magnetic field

AIP Advances, 2019
The InGaAs-InAlAs-InP high electron mobility transistor (InP HEMT) is the preferred active device used in a cryogenic low noise amplifier (LNA) for sensitive detection of microwave signals. We have investigated the angular dependence of the InP HEMT when

The X-ray fast-time variability of Sco X-2 (GX 349+2) with RXTE [PDF]

, 2001
Sco X-2 (GX 349+2) is a low-mass X-ray binary and Z source. We have analysed 156 ks of Rossi X-ray Timing Explorer data, obtained in 1998 January, on this source. We investigated the fast-time variability as a function of position on the Z track.
