    摘要： A system for measuring the stability of a power signal from a power supply includes a threshold violation detector. The threshold violation detector includes a comparator and an indicator. The comparator has a power signal input, a threshold signal input, and a comparison result output, and is configured to compare the power signal on the power signal input with a threshold on the threshold signal input to present a comparison result signal on the comparison result output. The indicator has a threshold violation output and a comparison input that receives the comparison result signal from the comparator. The indicator presents a threshold violation signal on the threshold violation output when the comparison result signal indicates that the power signal has violated the threshold.

    摘要： A comparator to provide an output voltage indicative of comparing an input voltage with a reference voltage, where the comparator has an asymmetric frequency response. With an asymmetric frequency response, the bandwidth of the input voltage may be greater than the bandwidth of the reference voltage. A comparator includes a differential pair of transistors coupled to a current mirror and biased by a current source, where in one embodiment, a capacitor shunts the sources of the differential pair. In a second embodiment, a capacitor couples the input voltage port to the gates of the current mirror transistors. In a third embodiment, the comparator utilizes both capacitors of the first and second embodiments.

    摘要： A method is described comprising conducting a first current through a switching transistor. The method also comprises conducting a second current through a pair of transistors whose conductive channels are coupled in series with respect to each other and are together coupled in parallel across the switching transistor's conductive channel. The second current is less than and proportional to the first current.
