Abstract
A high potential/high efficiency amplifier contains at least two separate amplifiers. One amplifier is used for the typical inputs that are received from an input source and a second amplifier is used solely for peak inputs. Utilizing the second amplifier to handle the peak inputs allows the first amplifier to concentrate solely on the typical inputs. A small resistor tied to the output of the second amplifier reduces the output of the second amplifier. Thus, when the output of the first and second amplifiers are equal, the output of the first amplifier will be applied to the load. When the input exceeds the operational value for the first amplifier, the first amplifier logically disconnects itself from the load and the output of the second amplifier is applied to the load. Once the input returns to a value within the limits of the first amplifier, the first amplifier becomes operational again, and the resistor again becomes a barrier to the second output being applied to the load.
