    Abstract: A power conserving phase-locked loop achieves power savings by adding a switch which selectively enables the bias current for the charge pump associated with the phase comparator of the phase-locked loop. The switch is connected by a logic circuit to a counter that tracks the expected arrival time of a signal edge of the reference signal. Immediately prior to the arrival of the expected signal edge, the switch is enabled, thereby creating and applying the bias current to activate the charge pump in the event that a correction is needed to maintain the "lock" in the phase-locked loop. When the signal edge passes, the bias current is turned off again before the arrival of the next signal edge. This switching may result in a ten percent duty cycle in the biasing current, resulting in approximately a ninety percent power savings. The phase-locked loop may be used for a variety of applications, such as a frequency synthesizer in a receiver chain of wireless communications mobile terminals, where power consumption is a concern.

    Abstract: Decoded data (7) are obtained by decoding a PCH (paging channel) by means of an RF receiver (3), and A/D converter (4), a correlator (5), and a decoder (6) by performing intermittent receiving operations during stand-by time. An intermittent reception control circuit (16) discriminates the presence/absence of paging data in the PCH based on control information near the lead edge of the PCH and, when no paging data exist, reduces the power consumption of intermittent reception by quickly stopping the functions of the receiver (3), converter (4), correlator (5), and decoder (6). Therefore, the stand-by time of battery-operated digital radio communication equipment can be prolonged.

    Abstract: In apparatus and a method of transmitting messages in predetermined time slots within fixed length time frames in which the power level of a message received at a receiver is detected. If the power level falls outside one of a series of ranges around a predetermined target power level, then the power level of the next message to be transmitted is adjusted so that the power level of the next message falls within the range. Steps of detection and possible-adjustment are repeated with increasingly fine target ranges of power levels being applied.

    Abstract: A receiver capable of receiving a plurality of signals, wherein more of the signals are received at a peak time than at an off peak time, comprises the method of a first step for determining if the signals are being received by searching in a first search mode and a second step for determining if the signals are not being received by searching in a second search mode. Selection circuitry activates the first step during the peak time and activates the second step during the off peak time. The first and second search modes comprise searching for the signal and searching for noise, respectively.
