    摘要: A leakage compensation approach enabling full VCC precharge. An array of memory cells is coupled between a pair of bit lines. A precharge circuit precharges the pair of bit lines to substantially a supply voltage level and a leakage compensation circuit supplies a first compensation current to a first one of the bit lines to substantially compensate for leakage current supplied by the first bit line during a memory access operation directed to one of the plurality of memory cells.

    摘要: A level shifting device comprises an input stage, a cascode stage, a cross-coupled stage, and an output stage. The input stage may receive a data signal or binary logic input in a first data range, a complement of the data signal, and a first voltage. The cascode stage may receive a first voltage and may be connected to the input stage. The cross-coupled stage may be adapted to isolate the first voltage and may be connected to the cascode stage. The output stage may receive a second voltage, provide an output, and be connected to the cross-coupled stage. The cascode stage may be adapted to provide the first voltage as the output when the logic input is a first value and provide the second voltage as the output when the logic input is a second value. Other embodiments are also claimed and described.

    摘要: A resonance suppression circuit is provided to suppress resonance on a power grid of a chip or die. The resonance suppression circuit may include a band-pass filter portion, a comparator portion, an amplification portion and a current dissipation portion. The band-pass filter portion may include an inverter coupled between two signal lines of the power grid. The comparator portion may sense voltage fluctuations at approximately the resonance frequency and trigger the current dissipation portion to turn ON and thereby change the frequency spectrum of the load current on the power grid to suppress the power grid resonance.
