  • Fully complementary folded cascode amplifier
    Patent number: 6043708
    Abstract: A method and apparatus for decreasing the supply current to peak output current ratio of a fully complementary cascode amplifier. The amplifier has two shunt portions coupled to a pair of differential input signals and to an output portion which, in turn, is coupled to a pair of output terminals. Based on the relative magnitudes of the input signals, the first shunt portion selectively diverts current from the output portion while the second shunt portion selectively supplies current to the output portion.
