Abstract: Various methods provide for trimming the gain in a dual-port phase-locked loop (PLL) of a radio transceiver. Use is made of the radio's demodulator to perform modulation accuracy measurements, thereby reducing the cost and complexity of external test equipment.

Abstract: A method, apparatus, and device provide for the control of the power sourcing capability of a power source that supplies power to a device. A detection element of the device is operable to dynamically detect a power sourcing capability of the power source. A control element of the device is operable to monitor the detected power sourcing capability of the power source and to control the power source to effect a change in the power sourcing capability of the power source in response to a determination that the detected power sourcing capability of the power source is in violation of a threshold value.

Abstract: A power-efficient neutralized signal amplifier 100 for use in ultra-low power narrowband receiver applications comprises a transformer 120 having a primary winding 122 and a differential secondary winding 124, coupled to an amplifier input 110; a gain cell 140, having a differential input 142 and a differential output 144, the differential input coupled to the transformer differential secondary winding and the differential output coupled to the amplifier output 160; and a neutralization element 150 coupled to the gain cell differential output and cross-coupled to the transformer differential secondary winding, where the coupling of the neutralization element to the differential secondary winding provides that the input impedance of the neutralized signal amplifier is substantially determined by reflected resistive parasitics of the transformer. The neutralization element may comprise neutralization capacitors (figure 2) or an output transformer coupled to the gain cell differential output (figures 3 and 4).

Abstract: A method, system, and device provide power-efficient communications within the context of available power. Transmission and receipt data rates are scalable in accordance with output power available from a power source. Data is transmitted at a data rate determined, at least in part, by the available output power.

Abstract: A method, apparatus, and device provide for the detection of the adequacy of the current sourcing capability of a power source. The current sourcing capability of the power source is dynamically detected by sampling comparison values obtained during one or more sampling sub-windows and determining a sample density of comparison values. In response to the sample density of comparison values crossing a selectable density threshold, an insufficient-supply indication is generated.
