  • Methods and apparatus to provide slew enhancement for low power amplifiers
    Patent number: 7446606
    Abstract: Methods and apparatus to provide increased current to a cascode amplifier to maximize slew rate are disclosed. The amplifier has a first input coupled to an input switch and a load circuit for amplifying an input voltage on the first input. A slewing input voltage to the amplifier is detected. Current is increased to the load circuit to increase the slew rate of an output voltage.
    Type: Grant
