摘要： In one embodiment, a battery management system includes a charger controller for controlling a charging current of a battery according to a status of a load which is powered by the battery, and a counter coupled to the charger controller for determining a charging time according to such status. Advantageously, a first charging current is selected when the load is off. A second charging current that is less than the first charging current is selected when the load is on. Furthermore, a frequency of the counter is set to a first frequency when the load is off. The frequency is set to a second frequency that is less than the first frequency when the load is on.

摘要： A power supply system can include a primary power supply coupled to an output, and a secondary power supply coupled to the output. The primary power supply provides power to the output when a voltage level of the secondary power supply is less than a first predetermined level. The secondary power supply provides power to the output when the voltage level of the secondary power supply is greater than the first predetermined level. The secondary power supply not only provides power to the output, but also charges the primary power supply when the voltage level of the secondary power supply is greater than a second predetermined level that is greater than the first predetermined level.

摘要： One embodiment of a laser driver for high speed interconnections includes a buffered level shifter to shift the input voltage level to an appropriate level. In some embodiments the buffered level shifter may be tuned to provide a desired level shift with impedance matched to the driving load. Another embodiment converts a digital signal to a current train of a bias mode to represent logical zero and of a modulation mode to represent logical one, wherein one or both of the bias mode and modulation mode may be adjusted, for example by a programmable control circuit or by an adaptive control circuit. Some embodiments also provide circuitry for reducing overshoot of the output signal.

摘要： A device includes a first circuit having rows and columns of delay cells to generate delayed signals based on an input signal. The delayed signals are selectable and have a different delay from one another with respect to the input signal. The device is programmable based on a delay code. Different values of the delay code allow the device to select different delayed signals. The device may select one of the delayed signals from the first circuit for use as a timing signal in a second circuit of the device. The device may also use the delayed signals from the first circuit to evaluate a clock and data recovery circuit. In an embodiment, the circuits may be located on a single die.
