  • Patent number: 7880531
    Abstract: Apparatuses, systems, and methods are disclosed for generating, regulating, and modifying various voltage levels on a semiconductor device using a current mirroring digital-to-analog voltage regulator. The voltage regulator operates by mirroring a reference current onto a selectable current level and controlling the selectable current level with a digital input to a plurality of switched CMOS devices connected in parallel. The switched CMOS devices generate the selectable current level responsive to the digital input and proportional to the reference current. The selectable current level is combined with an output of a voltage divider to generate a monitor signal. The monitor signal is compared to a reference voltage and the results of the comparison controls a charge pump to generate a pumped voltage. The pumped voltage is fed back to the voltage divider, which includes a feedback resistor and a reference resistor connected in series between the pumped voltage and ground.
