Abstract: PURPOSE: An apparatus for determining the state of an analog and a method thereof are provided to perform a higher speed operation compared to a determination circuit in a conventional digital method by adopting a current mode. CONSTITUTION: A three-state determining apparatus includes a switch array(110) and a 3-state determination part(120). The switch array includes switches of a UP-group and a DN-group. The switch is composed of an MOS device. The switch array transfers one output current corresponding to the difference of the switching number of the DN-group and the switching number of the UP-group to the 3-state determination part. The 3-state determination part changes output currents from the switch array into two state currents by using an analog type circuit consisting of current sources and MOSs(Metal Oxide Semiconductor). The 3-state determination part determines the switching state of the switch array by using two state currents.
