  • Method for outputting a current and current output circuit
    Patent number: 11736118
    Abstract: A method for outputting a current includes performing a sorting operation on a plurality of current sources according to intensities of currents generated by the current sources, dividing the plurality of current sources into N current source sets according to a result of the sorting operation and a predetermined selection order, and enabling at least one current source set of the N current source sets to output the current according a target output value. The plurality of current sources have a same target current value. Each of the N current source sets includes at least one current source. In the N current source sets, a total quantity of current sources of the nth current source set is twice a total quantity of current sources of the (n?1)th current source set.

  • Method for calibrating currents, current control system, and voltage control system
    Patent number: 11652404
    Abstract: A method for calibrating currents includes performing a first sorting operation on a plurality of first current sources according to current levels generated by the first current sources, performing a second sorting operation on a plurality of second current sources according to current levels generated by the second current sources, determining a first switching sequence for the first plurality of current sources according to a result of the first sorting operation, and determining a second switching sequence for the second plurality of current sources according to a result of the second sorting operation and the first switching sequence. The plurality of first current sources have a same target current value, and the plurality of second current sources have a same target current value.
