ABSTRACT:
An offset voltage measuring apparatus includes an offset voltage measuring unit including a plurality of measurement nodes having a current variation in response to a feedback voltage. An offset voltage amplifying unit outputs an output voltage amplified in response to an output signal of the offset voltage measuring unit, changes feedback voltage in response to a change in the output voltage and feeds back the feedback voltage to the offset voltage measuring unit.
