    Patent number: 10191507
    Abstract: An electronic device may include first through fourth current generators. The first current generator may be configured to output first and second mirroring currents. The second current generator may be configured to output third and fourth mirroring currents. The third current generator may be configured to generate a fifth mirroring current having a current slope proportional to a current slope of the first mirroring current and output a first current having a level of a value obtained by subtracting a level of the fifth mirroring current from a level of the second mirroring current. The fourth current generator may be configured to generate a sixth mirroring current having a current slope proportional to a current slope of the fourth mirroring current and output a second current having a level of a value obtained by subtracting a level of the sixth mirroring current from a level of the third mirroring current.
