Abstract
A novel technique for designing micropower operational amplifiers is described. An amplifier that operates in two separate states-sleep-mode and awake mode-is presented. Although the amplifier draws only 40 μA of drain current while operating in the sleep-mode, it is able to drive 50 mA of output current when it transitions to the awake-mode. Transition between the two states is automatic, depending on the output current driving requirement
