Differential current sensor
The invention relates to a differential current sensor for measuring a differential current (Δi) between an electric current (ih) through a delivery conductor (h) and an electric current (ir) through a return conductor (r), with two low-ohmic current-measuring resistors (rh, rl) for measuring the currents (ih, ir) in the delivery conductor (h) and return conductor (r) and two measuring devices (meh, mel) with a measuring transducer for measuring the voltage drops (uh, ul) over the two current-sense resistors (rh, rl) in each case, and also with two voltage references (urefh, urefl) for calibrating the measuring devices (meh, mel). It is suggested that the two measuring transducers successively measure both the voltage drop (uh) over the respective current-sense resistor (rh) and the associated voltage reference (urefh, urefl)..

Mems process and device
A method of fabricating a micro-electrical-mechanical system (mems) transducer comprises the steps of forming a membrane on a substrate, and forming a back-volume in the substrate. The step of forming a back-volume in the substrate comprises the steps of forming a first back-volume portion and a second back-volume portion, the first back-volume portion being separated from the second back-volume portion by a step in a sidewall of the back-volume.
