摘要: A sensing circuit (120) for sensing currents, including: a measure circuit branch (132i), 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 (132o), 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 (140) for comparing the input and comparison voltages, and a comparison current generating circuit (N3s, 135; N3s, 135′; N3s, 135″) for generating the comparison current based on a reference current (Ir). The comparison current generating circuit includes at least one voltage generator (135; 135′; 135″). A memory device using the sensing circuit and a method are also provided.
