Abstract
A sensing circuit () for sensing currents, including: a measure circuit branch (), having a measure node for receiving an input current (Ic) to be sensed, for converting the input current into a corresponding input voltage (V−); at least one comparison circuit branch (), having a comparison node for receiving a comparison current (Igs), for converting the comparison current into a corresponding comparison voltage (V+); and at least one voltage comparator () for comparing the input and comparison voltages, and a comparison current generating circuit (N; N; N″) for generating the comparison current based on a reference current (Ir). The comparison current generating circuit includes at least one voltage generator (). A memory device using the sensing circuit and a method are also provided.
