摘要： Embodiments of an adapter are disclosed that include a transformer with a primary coil coupled to an H-bridge. The H-bridge is controlled by a control circuit that controls a voltage across the primary coil using the H-bridge, and the control circuit is configured to control the H-bridge so that during each of one or more intervals, a first voltage pulse is applied across the primary coil in a start direction, wherein the start direction alternates between a first direction and a second direction each interval. Then, a direction of subsequent voltage pulses across the primary coil is alternated between the first direction and the second direction a predetermined number of times. After the predetermined number of times, a last voltage pulse is applied across the primary coil; then, voltage across the primary coil is reduced to zero for a predetermined time.

摘要： A mismatch shaped analog to digital converter. The novel analog to digital converter includes a first circuit for providing a plurality of reference voltages, a plurality of comparators adapted to compare an input signal with the reference voltages, and a second circuit for randomizing connections between the reference voltages and the comparators. The connections are randomized such that noise caused by mismatch errors is spectrally shaped according to a desired noise-shaping characteristic. In an illustrative embodiment, the second circuit includes a noise-shaping circuit comprised of a plurality of Delta-Sigma modulators for generating one or more control signals, and a router for connecting the reference voltages to the comparators in accordance with the control signals. The mismatch shaped analog to digital converter can be used within a Delta-Sigma modulator to shape noise caused by mismatch errors in the feedback digital to analog converter.

摘要： A comparator uses two resonant tunneling diodes (RTDs) in series with resistors of the latch element of the comparator. By inserting two RTD diodes in series with resistors, the negative resistance of the first and the second RTD diodes reduces the effective RC time constants of the resistors and latch, leading to a faster regeneration during a latching mode of the comparator than achieved with alternative designs.
