  • Techniques to reduce memory effect or inter-symbol interference (ISI) in circuits using op-amp sharing
    Patent number: 8680915
    Abstract: An amplifier system and method that eliminates memory effects due to amplifier sharing. The amplifier has a plurality of input stages. An input to be amplified is applied to one of the input stages of the amplifier, while the other input stages are turned off and reset. The inputs of the unused input stages are thus reset and equalized while the other input stage is turned on to receive the input to be amplified. An explicit reset phase is not needed.
