  • Abstract
    In this paper the challenge of improving the energy-efficiency of comparators is addressed, by proposing a novel comparator structure, to be used in ultra-high-speed ADCs. In this comparator, the pre-amplification is embedded in the input switched-capacitor network by using the passive-amplification capability of MOS devices. Simulated results show that this comparator exhibits low-offset ultra-fast regeneration-time and high energy-efficiency.
