摘要： A portable phone has an internal battery and an external battery pack that is releasably attachable to the phone. A control unit in the phone controls connection of the respective batteries to a phone power input, depending on the detection of the external battery voltage. Whenever an external battery is present with a voltage above a predetermined minimum value, the external battery will be connected to the phone power input to provide power to operate the phone, so that the internal battery lifetime is extended. When the external battery voltage falls below the minimum value, or the external battery is removed, the unit automatically switches to internal battery power, so that the external battery can be changed without interrupting power supply to the phone, if the phone is on or during a call. An improved multi-phase software controlled battery-charging method and apparatus is used to charge the internal and external battery packs. The preferred battery-charging method uses a multi-phased charging approach comprising a trickle-charging phase, a fast-charging phase, and a top-off charging phase. The internal battery is charged to near-full capacity by trickle-charging (when required) and subsequently fast-charging the battery. The external battery is similarly charged to near-full capacity. Thus, both batteries are charged to near-full capacity in a substantially reduced charging time period as compared with the total charging time.

摘要： A system and method for a multi-band direct conversion wireless communication receiver is presented. The system incorporates a low noise amplifier (LNA) configured to amplify received RF signals, a local oscillator (LO) configured to output a frequency, and I and Q channel mixers. Each mixer has a first input operatively coupled to the LNA, a second input operatively coupled to the LO output, and an output. The system further includes an adjustment mechanism configured to adjust drive level of the LO depending on a level of jammers detected by the receiver. Thus, the receiver may operate in multiple wireless communication bands and modes and meet the associated specifications.

摘要： An automatic gain control (AGC) and D.C. offset correction method and apparatus for controlling signal power of a received RF signal within a dual mode quadrature receiver is disclosed herein. In a preferred implementation the automatic gain control apparatus may be adjusted to provide a desired control response to various fading characteristics of a received FM, FSK, GMSK, QPSK, or BPSK signal. The AGC apparatus includes an adjustable gain amplifier having an input port for receiving an input signal, a control port for receiving a gain control signal, and an output port for providing an output signal. A quadrature downconverter coupled to the output port serves to translate the frequency of the output signal to a baseband frequency, thereby producing baseband signals. In a preferred implementation the downconverter is operative to map the carrier frequency of the output signal to a baseband frequency offset by a predetermined margin from D.C. Two high gain active lowpass filters provide out-of-band signal rejection for the baseband signals. A D.C. feedthrough suppression loop, disposed to receive said baseband signal, suppresses D.C. offsets produced by the downconverter and lowpass filters, hence providing a compensated baseband signal. The AGC apparatus is further disposed to generate a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and produces the gain control signal by integrating or by refraining from integration based on values of the reference, received power signal, and gain control signals, thereby extending the usable dynamic range of the receiver for FM mode.

摘要： An automatic gain control (AGC) apparatus for a digital receiver is disclosed herein. The AGC apparatus includes an adjustable gain amplifier having an input port for receiving an input signal, a control port for receiving a gain control signal, and an output port for providing an output signal. The AGC apparatus further includes a measurement circuit for generating a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and generates an gain control signal in response to a result of the comparison. The saturating integrator includes a decision circuit for enabling integration based on values of the received power signal, the reference signal, and the gain control signal. In a preferred implementation the utilization of an input limiter in conjunction with an analog to digital converter enables accommodation of an increased input signal dynamic range. Accordingly, the AGC apparatus is capable of being used in digital demodulation of FM signals. The AGC apparatus may also be employed within a dual mode receiver designed to process both FM and code division multiple access (CDMA) input signals.

摘要： A battery protection circuit for an external battery pack has a switch for controlling connection of a battery output to a load and a detector for detecting a resistance at a load output terminal. A first comparator compares the detected resistance to a predetermined maximum value, and a second comparator compares the detected resistance to a predetermined minimum value. If the detected resistance is in the range between the minimum and maximum values, a control signal is produced to enable connection of the battery output to the load. If the detected resistance is outside the range, the switch is disabled and no current can flow to the load.

摘要： A system and method for generating a local oscillator (LO) frequency in a zero intermediate frequency (IF) receiver or transmitter is presented. A signal is received from a voltage controlled oscillator (VCO). The signal has a VCO frequency. The VCO frequency is divided by a number N to produce a signal having a divided-down frequency. The signal having the VCO frequency is then mixed with the signal having the divided-down frequency to produce an output signal having an output frequency. Local oscillator leakage is reduced. Thus, the receiver or transmitter may operate in multiple wireless communication bands and modes and meet the associated specifications.

摘要： The method and apparatus of the present invention improve the immunity to interference of a radio receiver. The power level of a received signal is detected. If the power level meets or exceeds a predetermined power threshold, the low noise amplifier is by-passed, thus increasing the intercept point of the receiver components.Alternative embodiments include the use of an RF power detector to control the front-end gain as a function of jammer power. In lieu of a switchable RF gain block, several methods of continuous gain control are proposed. Continuous gain control allows the interference suppression and sensitivity of the receiver to be adjusted at lower signal levels than the switchable gain block.
