Abstract: A closed loop amplifier adapted to be directly connected to a battery having a battery voltage for powering the amplifier. The amplifier includes an amplifier stage having a node for receiving a control voltage for controlling a common mode voltage of the stage, a digital voltage indicator for generating a digital value corresponding to the battery voltage, and a common mode voltage supply providing the control voltage corresponding to the digital value.

Abstract: The summing comparator includes: a first integrator; a second integrator for receiving an output of the first integrator; and a comparator for switching when the output of the first integrator is greater than the output of the second integrator. The outputs of the first and second integrators are directly compared by the comparator without the necessity of a summing amplifier.
