Abstract: Circuits and methods to provide an LDO output stage implemented with low-voltage devices and still allowing higher voltage levels have been achieved. The output stage has been built using two low voltage MOS devices in series. During the time the regulator is in active mode the second MOS device acts as a small resistor in series to the pass device. During power down this second device actively protects the MOS pass device and itself from high voltage stress levels. This is achieved by a robust regulating mechanism that compensates leakage currents. These leakage currents normally determine the different potentials of the output stage during power down. Although the second transistor presents a resistive obstacle during active mode the total chip area required is smaller compared to a single pass device tolerating e.g. 5 Volts.

Abstract: A method for dynamically adapting the biasing current for a fast switching CMOS comparator is achieved. The difference of the two input signals of said comparator controls the comparator's biasing current, where the biasing current is high only when the difference is low and the comparator's switching is likely to happen and where the biasing current is kept low at other times. In a current mirroring circuit, the voltage difference at the comparator inputs controls the mirroring ratio. The biasing current reaches its maximum when the input voltage difference approaches zero. Once the input voltage difference crosses zero and continues to change in the same direction as before, that is after the polarity of the voltage difference changed, the control mechanism alternates the connection of the comparator input signals to the current controlling elements, in order to now reduce the current with a further increase of the voltage difference.
