Abstract: A battery-optimized system-on-a-chip includes multimedia module, a high-speed interface, a processing module, on-chip memory, and an on-chip DC-to-DC converter. The multimedia module operably coupled to produce rendered output data from input data received via the high-speed interface and/or from data stored in the on-chip memory. The high-speed interface is operably coupled to provide data to and from an external source. The on-chip memory is operably coupled to store at least a portion of a multimedia application, wherein the processing module processes input multimedia data in accordance with the multimedia application to produce output multimedia data. The on-chip DC-to-DC converter is operably coupled to convert a battery voltage into a supply voltage that is provided to the multimedia module, the high-speed interface, the processing module, and/or the on-chip memory.

Abstract: A differential line driver that includes a 1st operational amplifier, a 2nd operational amplifier, an adjustable reference module, a 1st feedback impedance, and a 2nd feedback impedance. First inputs (e.g. the inverting input or non-inverting input) of the 1st and 2nd operational amplifiers are coupled to receive an input signal. The 2nd inputs (e.g. the compliment of the 1st input) of the 1st and 2nd operational amplifiers are operably coupled to receive an adjustable reference voltage from the adjustable reference module. The adjustable reference module provides the adjustable reference voltage based on the common mode of the power source for the 1st and 2nd operational amplifiers (e.g. Vdd, Vss) and/or the common mode of the input signal. The 1st and 2nd feedback impedances, (e.g. resistors) are coupled from the output of the respective operational amplifiers to either the 1st or 2nd input of the respective operational amplifiers.
