Abstract: Current-generation circuitry, comprising: a plurality of candidate current sources operable to generate respective candidate currents; an output current source operable to generate an output current; comparator circuitry; and control circuitry operable to control the current sources and the comparator circuitry to: in an adjustment step, generate an adjustment current by selecting one of the candidate currents or by summing together a plurality of the candidate currents, and calibrate at least a plurality of the candidate current sources; and in a calibration step, following the adjustment step, generate a reference current by selecting one of the candidate currents generated by the candidate current sources calibrated in the adjustment step or by summing together a plurality of the candidate currents generated by those candidate current sources, and calibrate the output current source by comparing its output current to that reference current and adjusting a control signal applied to that output current source.
