    摘要: Circuits and methods for calibrating offset error in a differential amplifier in an efficient and reliable way are described. A final calibrated state for the differential amplifier is obtained in accordance with a nonlinear search that requires significantly fewer test stages to complete than linear search methods. As a result, longer test periods may be used with the invention without adversely affecting the overall length of the calibration process. Because circuit conditions near the calibration point cause internal test signals to switch more slowly from one state to another, lengthening the test period time may allow more time for the internal test signals to reach their final values and, thereby, improve calibration accuracy.

    摘要: In one embodiment, path data is received. The path data is indicative of a plurality of connectivity paths to electronically connect a computer and a printer. A graphic user interface is provided for display to a user, the interface to enable sending of print jobs to a print queue. The queue is to hold the print jobs to be sent to the printer, and is without limitation to a specific path among the plurality of paths. A command for the computer to send a first print job to the printer is received via the interface. The plurality of paths is monitored to identify an available path among the plurality of paths. The first print job is caused to be sent from the queue to the printer via the available path.
