  • Dynamic biasing techniques for low power pipeline analog to digital converters
    Patent number: 6462695
    Abstract: A method and circuitry for implementing low-power analog-to-digital converters. More particularly, embodiments of the present invention provide an amplifier circuit for pipeline ADCs having multiple stages, some in sample mode, some in hold mode. The stages include residue amplifiers which include a pre-amp and a current source. The current source is turned off during the sample mode. Some embodiments include a second current source that provides a bleeder current during the sample phase so that the pre-amp remains in steady state.
