Abstract
A high gain, high speed rail-to-rail amplifier that comprises two symmetrical input stages: an n-input stage responsive to middle and high range input voltages and a p-input stage responsive to low and middle range input voltages. A gain stage, in electrical communication with each of the input stages, receives current from the n-input stage when the input voltage signal is in the middle or high ranges and receives current from the p-input stage when the input voltage signal is in the low or middle ranges to provide amplification of the input voltage signal at the upper and lower ends of its range and provide increased amplification in the middle range. The amplifier further includes an output stage that includes two MOS transistors that cooperate to increase the output signal range and to provide the amplifier with increased driving ability.
