    摘要: A system and method for protecting a circuit. The system includes a protection circuit that includes an inverter and a capacitor coupled to the inverter. The inverter and the capacitor are implemented using logic circuits of a circuit core, and the inverter shunts electrostatic discharge ESD current through the capacitor. According to the system and method disclosed herein, because the protection circuit shunt circuit shunts ESD current using logic circuits of the circuit core, ESD protection is achieved while not requiring large FETs. Also, the protection circuit protects circuits against ESD events that conventional FET cannot protect.

    摘要: Various embodiments of the present invention provide systems and methods for analog to digital conversion. For example, a retimed analog to digital converter is disclosed that includes a first set of sub-level interleaves and a second set of sub-level interleaves. The first set of sub-level interleaves includes a first sub-level interleave with a first set of comparators synchronized to a first clock phase, and a second sub-level interleave with a second set of comparators synchronized to a second clock phase. The second set of sub-level interleaves includes a third sub-level interleave with a third set of comparators synchronized to a third clock phase, and a fourth sub-level interleave with a fourth set of comparators synchronized to a fourth clock phase. A global interleave selects one of the first set of comparators based at least in part on an output from the second set of sub-level interleaves, and one of the third set of comparators based at least in part on an output from the first set of sub-level interleaves. In some instances of the aforementioned embodiments, an output of the first sub-level interleave and an output of the second sub-level interleave are synchronized to the third clock phase, and an output of the third sub-level interleave and an output of the fourth sub-level interleave are synchronized to the first clock phase.
