Abstract
Embodiments of the invention generally provide an device that regulates a negative output voltage from a power supply using a positive representation of the negative output voltage. To convert the negative voltage to a positive voltage, the device changes the negative voltage into a current using, for example, a current generator that outputs a current corresponding to the negative voltage received from the power supply. This current is then transferred from the negative voltage domain to the positive voltage domain and is fed through a voltage generator that outputs a positive voltage corresponding to the current. By doing so, the negative voltage output is transformed into a corresponding positive voltage. This positive voltage may then be compared to a positive reference voltage to determine an error signal for adjusting the power supply.
