Abstract
Embodiments of a calibration circuit for a current source which may include a first control switch, a second control switch, and a capacitor. In embodiments, the first control switch may be operable to couple the capacitor to the current source and the second control switch may be operable to couple the capacitor to a reference current source to enable the capacitor to be charged or discharged according to a first control signal provided to the first control switch and a second control signal provided to the second control switch. In embodiments, the calibration circuit may be included in a digital-to-analog (DAC) converter.
