Abstract
A method for processing signals may include comparing an output voltage signal in an output stage of an amplifier with a reference voltage signal. If the output voltage signal is greater than the reference voltage signal, a comparator voltage signal may be generated. Bias voltage for at least one output stage transistor may be increased by increasing current generated by a first bias current source of the at least one output stage transistor. The current may be increased in proportion to the generated comparator voltage signal. The output voltage signal may be divided prior to the comparing. The at least one output stage transistor may be dynamically biased based on the generated comparator voltage signal. The comparator voltage signal may be generated using at least one differential pair with a current mirror load.
