Abstract: This design utilizes acoustic interference and intelligent recognition technologies to introduce a low-cost and low-power portable blocking recording and shielding system. It consists of a ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

In physics and materials science, the term "spin chirality" refers to an asymmetry in the arrangement of spins (i.e., the intrinsic angular momentum of particles) in magnetic materials. This asymmetry ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

Abstract: This paper presents bandgap reference (BGR) and sub-BGR circuits for nanowatt LSIs. The circuits consist of a nano-ampere current reference circuit, a bipolar transistor, and proportional-to ...
