A comparison of polar transmitter architectures using a GaN HEMT power amplifier

In this paper three transmitter architectures are compared, that each use the low-frequency envelope and high-frequency phase component of an RF signal. A power amplifier (PA) with Pulse Width Modulation by Variable Gate Bias (PWMVGB) is compared to an Envelope Elimination and Restoration (EER) and Envelope Tracking (ET) configuration. The test circuit is implemented using a discrete GaN HEMT powe

Per Ströms rapport Med storebror i uppfinnarverkstan från stiftelsen Den nya välfärden pekar på övervakningssamhället som ett hot mot demokratin och den enskildes integritet. Men integritetsidealet kanske bör se helt annorlunda ut än vad Ström anser. Det skriver Mikael Sundström, universitetslektor i statsvetenskap vid Lunds universitet.

Development and characterization of electrochemical cantilever sensor for bio/chemical sensing applications

We report the improvements made to our previously developed electrochemical cantilever (EC) sensor, where nanoporous gold material is employed as working electrodes in microcantilever arrays, while combined counter-reference electrodes are integrated on the chip. For a surface stress change of 1mN/m induced on the microcantilever, the cantilever deflects is 7.3 nm at the free end, indicating high
