Abstract
A multiple stage adaptive bias error amplifier has been developed for a linear voltage reducer that should regulate for a very large and continuous supply-voltage range between 1.2 and 3.6 V. It uses both the 3.3 V high voltage transistors available in the considered generic 0.18 μm logic process to allow above 1.8 V functioning and the normal transistors needed to reach the desired performance at the lowest supply voltages. The proposed multiple stage approach solves the contradictory requirements for low and high supply voltages, reduces the amplifier power consumption to less than 1.35 % of the load current and shows good regulator stability in spite of an increased number of poles.
