Abstract:
A voltage supply unit including a regulator unit, a voltage divider and a first current mirror. The regulator unit is configured to receive a first voltage signal and a second voltage signal, and is configured to generate a third voltage signal. The voltage divider is connected between the first current mirror and the regulator unit, and controls the second voltage signal. The first current mirror is connected to the regulator unit, an input voltage supply and the voltage divider. The first current mirror is configured to generate a first current signal and a second current signal, the second current signal is mirrored from the first current signal, the first current signal is controlled by the third voltage signal and the second current signal controls an output voltage supply signal.
