A buck converter is a step down DC/DC converter used in portable electronic devices to convert higher DC voltages to small voltages necessary to function. Lossless load current sensing ability is one of the most desirable features of contemporary current or voltage mode controlled DC/DC converters. Recently, current sensing techniques in DC/DC converters...

Nanopores are orifices of nanoscale diameter that connect two fluid reservoirs. At these dimensions, even a single molecule passing through the nanopore generates a detectable change in the flow of ionic current through the pore. As a result, nanopores can function as nanoscale Coulter counters, sensory devices that measure the effective change...
