Abstract
A voltage regulator has a comparator and a reference voltage coupled to a first input of the comparator. An output voltage of the voltage regulator is coupled to a second input of the comparator through a resistor. A current source is coupled to the second input of the comparator. The first current source can be a first digital-to-analog converter (DAC). A second current source can be coupled in parallel with the first DAC. The second current source can be a second DAC. The voltage regulator can include a boost topology.
