Abstract (en)
[origin: EP1439443A1] The circuit has a first supply voltage input connected to a first comparator and a first voltage regulator, whereby the first comparator controls the first voltage regulator, a second supply voltage input connected to a second comparator and voltage regulator, whereby the second comparator controls the second voltage regulator, a supply voltage output connected to the outputs of both voltage regulators and fed back to both comparators. The circuit has a first supply voltage input (IN1) connected to a first comparator (CMP1) and a first voltage regulator (REG1), whereby the first comparator controls the first voltage regulator, a second supply voltage input (IN2) connected to a second comparator (CMP2) and voltage regulator (REG2), whereby the second comparator controls the second voltage regulator, and a supply voltage output (O) connected to the outputs of both voltage regulators and fed back to both comparators. AN Independent claim is also included for a method of generating a supply voltage.
