Abstract
A current difference divider circuit with a plurality of current sources is provided. The divider circuit includes a first current source which is operable to generate a first current, a second current source for generation of a second current less in magnitude than the first current, and a third current source for generating a difference current with its magnitude equivalent to a difference between the first and second currents and for generating a third current resulting from the division thereof. The circuit further includes a fourth current source for generating a fourth current obtainable by mirroring of the second current. The third and fourth currents are added together to provide a fifth current, which is then output.
Claims4
A current difference dividing circuit comprising:
- a first current source for generation of a first current;
- a second current source for generating a second current less than the first current;
- a third current source for generating a difference current of the first current and the second current and for generating a third current resulting from division thereof;
- a fourth current source for generating a fourth current obtained by mirroring of the second current;
- and
- a circuit which adds the third and fourth currents together to thereby provide a fifth current for output.
