Abstract: A deadtime generator configured to output a pair of non-overlapping clock signals. A circuit is provide that includes an input node for receiving a clock signal; a first signal path coupled to the input node and having a first output node for outputting a first modified clock signal, wherein the first signal path includes a feedback node coupled to an input of a feedback inverter; a second signal path coupled to the input node and having a second output node for outputting a second modified clock signal, wherein second signal path includes a Low-to-High skewed inverter; and a feedback signal path coupled to second signal path and having a High-to-Low skewed inverter with an output coupled to a gate of at least one transistor, wherein an output of the at least one transistor is coupled to the feedback node.

Abstract: Systems, methods, and other embodiments associated with error resolution and auto-correction are described. In one embodiment, a method includes, for a selected application that was executed by the computing system, accessing a system error log and identifying error messages that occurred during execution. Skipped data records that were not processed are identified. A resolving function is executed to resolve a selected error type that is associated with a group of skipped data records by: identifying an error pattern from an error message and matching it to a database of observed error patterns. In response to a match, retrieving a corrective action that is assigned to the observed error pattern and executing the corrective action to resolve the error on the group of skipped data records. The skipped data records are re-submitted and reprocessed where previous error should be resolved.

Abstract: Disclosed is a thermal stabilization circuit including a heater, which is adjacent and thermally coupled to a closed-curve waveguide of an optical ring resonator, and an analog feedback circuit, which includes a fully autonomous analog feedback loop from a drop port of a bus waveguide of the optical ring resonator to the heater. This analog feedback circuit is configured to dynamically control the electrical power provided to the heater and, thereby to dynamically control the thermal output of the heater in order to tune the ring resonance wavelength to the operating laser wavelength. The analog feedback circuit is further configured to be independent of input power, to be power efficient, to have a relatively small footprint, to have a tunable time constant and to facilitate adjustable wavelength locking. Also disclosed is a device (e.g., a ring-based transceiver or the like), which includes multiple optical ring resonators and corresponding thermal stabilization circuits.

Abstract: Embodiments of the disclosure provide a peak voltage detection circuit with reduced charge loss. A circuit structure of the disclosure includes a peak voltage detector having a first input node coupled to an input line and a second input node coupled to a first electrically actuated switch.
