ABSTRACT:
Analog voltage drain with reduced current drain is achieved by a new capacitive-divided feedback architecture. During the operational phase an op amp monitors a capacitively-divided fraction of the output voltage, and drives a current sink or source accordingly; during an initial phase the output is forced to the correct value by a different circuit, while the opamp is connected to self-tune itself in a way which removes DC offset effects.
