  • Patent number: 7855671
    Abstract: The present invention is related to a pipelined analog-to-digital converter (ADC) utilizing a power distribution scheme selectively delivering both constant and variable reference currents in selected proportions to a plurality of stages and operational transconductive amplifiers (OTAs). This permits the ADC to maintain an optimized speed over power consumption ratio over a wide data rate range. Since the invention is capable of supporting a large operating range while maintaining very low power consumption relative to the data rate, the pipelined ADC in accordance with the present invention is particularly adaptable to a large number of applications.
    Type: Grant
