Abstract: A portable data device employs an integrated circuit having a signal process or (112) that receives a power signal from an external source (308) via a power node. A decoupling device (304) is placed between t he power node and the signal processor (112). An energy reservoir (307) is placed in parallel with the signal processor (112), which acts in concert with the decoupling device (304) to isolate the effects of the signal processor (112) from the rest of the integrated circui t.

Abstract: An improved auto-zeroing feedback control circuit (FIG. 1) is disclosed to compensate for DC offset voltages in signal coding applications. The feedback control circuit for a signal limiter (120) includes a digital integrator (130) which oversamples the limited output (125). When the accumulated sample count overflows, an analog integrator (140) is enabled, and a small quantity of charge is delivered to the integrating capacitor. The analog integrator output signal (145) is then attenuated (150) and used to adjust the bias for the limiter (120). This improved auto-zeroing technique eliminates the requirement of a large external auto-zero capacitor, and permits the signal coder to be fully integrated on-chip.

Abstract: In a communication unit the receiver receives a signal (118) having desirable data (word A) and undesirable data (word B). The receiver (104) has a discontinuous receive mode of operation wherein the receiver (104) is turned on when expecting the desirable data (word A) and turned off when expecting the undesirable data (word B). A duration of time that the receiver (104) has been turned off is determined. The receiver (104) is turned on at a time prior to the arrival of the desirable data (word A) responsive to the duration of time that the receiver (104) has been turned off. Thus the turn on time more closely approaches the time taken by the receiver to stabilize, resulting in power saving.

Abstract: A level detector detects an input signal lever (205). A rectifier (210) receives the input signal and provides a rectified signal (215). A prefilter (220) receives the rectified signal and attenuates high frequency components at frequencies near multiples of a decimation sample rate. The prefilter signal (225) is decimitated by a decimator (230) and low pass filtered by a low pass filter (240) having a passband below the input frequency of the input signal. The level detector can be provided to control a variable gain stage circuit which applies a gain to the input signal based on the level to form a dynamic range compressor or expander.
