Abstract

The mosfet based power operational amplifier was developed for voice coil driven disk drives, that run on +5 volt and +12 volt power supplies. The +6 volts is developed from +12 volts on the disk drive. The design objective was to increase the closed loop bandwidth without increasing the crossover distortion or saturation recovery time.
