Abstract: A portable data device (400) having a power controller (430), a clock generator (428) and a digital circuit (432). The power controller (430) has an output signal. The output signal is representative of available power. The clock generator (428) is coupled to the output signal of the power controller (430) for generating a variable clock rate corresponding to the output signal. The digital circuit (432) is coupled to the clock generator (428), and the digital circuit (432) is controlled by the variable clock rate.

Abstract: A portable data device employs an integrated circuit having a signal processor that receives a power signal from an external source via a power node. A decoupling device is placed between the power node and the signal processor. An energy reservoir is placed in parallel with the signal processor, which acts in concert with the decoupling device to isolate the effects of the signal processor from the rest of the integrated circuit.
