Abstract
A current-sense amplifier with low-offset adjustment and a low-offset adjustment method thereof are disclosed. The current-sense amplifier includes a sensing unit, an equalizing unit and a bias compensation unit. The sensing unit includes a sense amplifier, a latch circuit, a first precharged bit line, and a second precharged bit line. The equalizing unit is electrically connected to the first and the second precharged bit line for regulating a voltage of the first precharged bit line and a voltage of the second precharged bit line to the same electric potential. The bias compensation unit is electrically connected to the sense amplifier for compensating an input offset voltage of the current-sense amplifier.
