Abstract: A method of charging a battery includes applying a charging current from a semiconductor device to the battery during a first battery charging time period. The method also includes measuring a charging voltage level at the battery during the first battery charging time period. During a non-charging voltage measurement time interval, the method includes temporarily stopping application of the charging current from the semiconductor device to the battery and measuring a non-charging voltage level at the battery while the charging current is not being applied to the battery.

Abstract: A method for reducing distortion caused by clipping of lower frequency audio signals begins by monitoring a volume setting of an audio signal with respect to a range of volume settings to produce a monitored volume setting. The method continues by establishing an equalization setting based on the monitored volume setting.

Abstract: A semiconductor device includes an adjustable current source that is coupled to an external battery. The semiconductor device includes a feedback control module that is responsive to a voltage level at the external battery. The feedback control module also has an output that is directed to control the current supplied by the adjustable current source. Also, the feedback control module can selectively provide a signal to periodically and temporarily turn off the current supplied by the adjustable current source. A voltage at the external battery is measured during a time period when the current is turned on and during a time period when the current is turned off. While the current is turned off, the feedback control module can measure the external battery voltage so that it can be compared to the battery voltage while the adjustable current source is on.

Abstract: A system-on-a-chip integrated circuit includes a multimedia module that produces rendered output data and a high-speed interface. A processing module generates output multimedia data in accordance with at least a portion of a multimedia application in response to input multimedia data received from either the multimedia module or the high-speed interface. The output multimedia data is provided to either the multimedia module or the high-speed interface. An on-chip DC-to-DC converter converts a battery voltage into a supply voltage that is coupled to the multimedia module, the high-speed interface, and/or the processing module.

Abstract: A level shifter includes a first level shift module for producing a shifted signal by adjusting a direct current (DC) level of an input signal by a first bias voltage having a first polarity. A second level shift module produces an output signal by adjusting a DC level of the shifted signal by a second bias voltage having a second polarity. The first polarity is opposite to the second polarity and the sum of the first bias voltage and the second bias voltage is a non-zero voltage.
