摘要： The voltage applied to an integrated circuit is controlled by a temporal process monitor formed as part of the integrated circuit. The temporal process monitor includes a voltage controlled oscillator for producing a first output signal having a first period. A comparator compares the first period to one or more reference values. Should the first period be greater than a first selected reference value the comparator sends a signal to increase the voltage being supplied to the integrated circuit. Should the first period be less than a second selected reference value, the comparator sends a signal to decrease the voltage applied to the integrated circuit. In some embodiments a scaling circuit is provided for producing a second output signal having a second period different from (typically but not necessarily longer than) the first period. By placing the temporal process monitor on an integrated circuit chip, process variations and environmental factors which affect the performance of the integrated circuit can be automatically compensated so that the integrated circuit performs within specifications. Two or more temporal process monitors can be placed on a single integrated circuit chip or on different integrated circuit chips and the longest period produced by the temporal process monitors can be used to control the voltage supplied to all the sections of the integrated circuit chip associated with the temporal process monitors or to all the integrated circuit chips associated with the temporal process monitors.

摘要： A method for charging a battery is disclosed, wherein a constant current charging current is periodically adjusted as needed such that the change in battery voltage increases approximately linearly during the charging period. In some embodiments the charging is in three phases. An optional first phase charges with a low current until the battery voltages rises to a certain minimum. During a second phase a constant current is provided while the battery voltage is monitored. The second phase constant current is periodically increased if the rate of change of battery voltage is less than a predetermined value and is decreased if the rate of change of battery voltage is more than the predetermined value. When the battery voltage attains a predetermined value, a third phase begins wherein a constant voltage is applied to the battery while the battery current draw is periodically monitored. Charging is stopped when the battery current draw falls to a predetermined value or, in some embodiments, when the charging current drops to a value that is a certain percentage of the charging current at the termination of phase two.In one embodiment the battery voltage is monitored to determine a possible battery failure, for example in the case of the battery voltage decreasing during the constant current charging of phase two. In some embodiments the battery is shorted out in response to detection of a possible failure.
