This paper presents an inductorless ultra-low power frontend for applications such as sensor networks and medical implants. By using a completely inductorless topology the chip area is just 0.017mm2, excluding pads. A real input impedance of 300Ω is achieved with current feedback. Manufactured in 65nm CMOS, it measures more than 17dB gain from 100MHz to 2000MHz while consuming only 175μW from a 0.

We find effective, or homogenized, material parameters for Maxwell’s equations when the microscopic scale becomes small compared to the scale induced by the frequencies of the imposed currents. After defining a singular value decomposition of the non-selfadjoint partial differential operator, we expand the electromagnetic field in the modes corresponding to the singular values, and show that only the

Due to organizational changes in the Swedish air navigation services (ANS), which in extension could impact flight safety, the safety culture (SC), organizational climate (OC), and related areas are monitored. Study locations are the two main air traffic control centers in Sweden and parts of the central ANS office. This paper reports on a first attempt to investigate whether relationships exist b
