摘要： Techniques for controlling operation of control loops in a receiver are described. The operation of at least one control loop is modified in conjunction with a change in operating state, which may correspond to a change in linearity state, gain state, operating frequency, antenna configuration, etc. A change in linearity state may occur when jammers are detected and may cause bias current of analog circuit blocks to be adjusted. The at least one control loop to be modified may include a DC loop, an AGC loop, etc. The operation of a control loop may be modified by disabling the control loop or changing its time constant prior to changing operating state, waiting a predetermined amount of time to allow the receiver to settle, and enabling the control loop or restoring its time constant after waiting the predetermined amount of time.

摘要： Techniques for operating a receiver to achieve good linearity performance and higher receive signal to noise ratio are described. The receiver includes one or more circuit blocks, e.g., a low noise amplifier (LNA), having discrete gain states. The gain states are selected based on switch points, with each switch point indicating a specific received signal level at which to switch from one gain state to another gain state. The switch points may be dynamically selected based on channel conditions, which may be characterized by the presence or absence or strength or frequency of jammers. A first set of switch points may be selected when jammers are detected, and a second set of switch points may be selected when jammers are not detected. The gain states are selected in accordance with the set of switch points selected for use.

摘要： An integrated circuit for achieving power reduction in a transceiver may include a jammer detector that determines an interference level corresponding to a received signal, and a transmit power detector that determines a required transmit power level for a transmitted signal. The integrated circuit may also include at least one of the following: a process monitor that determines process corners of components within the receiver and/or the transmitter, and a temperature monitor that determines a temperature of the receiver and/or the transmitter. The integrated circuit may also include a state machine. The state machine may transition the receiver from a high linearity mode to a low linearity mode if a set of operating conditions is satisfied. Similarly, the state machine may transition the transmitter from a high power mode to a low power mode if a set of operating conditions is satisfied.

摘要： Techniques for operating two receivers to receive data and paging from two systems are described. A primary receiver is associated with better performance than a secondary receiver under poor RF conditions. The two receivers may be operated in either a hybrid mode in which the primary receiver is used to receive paging or a simultaneous mode in which the second receiver is used to receive paging. One of the modes may be selected for use based on RF conditions, received power, demodulation metrics, and/or other criteria. In one design, a mode is selected based on the received power and one or more thresholds. In another design, the hybrid mode is selected for poor RF conditions and, for good RF conditions, the hybrid or simultaneous mode is selected based on received power.

摘要： PROBLEM TO BE SOLVED: To provide the requisite level of performance while minimizing power consumption.
SOLUTION: Power consumption is minimized on the basis of the measurement of non-linearity in an output signal from a receiver 1,200. The amount of the non-linearity can be measured by an RSSI slope or an energy-per-chip-to-noise-ratio Ec/Io value. The RSSI slope is the ratio of a change in the output signal plus intermodulation to a change in an input signal. The input signal level is periodically increased by a prescribed level and the output signal from the receiver 1,200 is measured. The output signal comprises a desired signal and intermodulation products from the non-linearity within the receiver 1200. When the receiver 1,200 is operating linearly, the output signal level increases dB per dB with the input signal level. However, when the receiver 1,200 enters into a non-linear region, intermodulation products caused by a non-linearity increase faster than the desired signal. By detecting the RSSI slope, the amount of degradation caused by the non-linearity can be determined. This information is then used to adjust the IIP3 operating point of an amplifier 1,234 and a mixer.

摘要： A receiver comprising a sigma-delta analog-to-digital converter (.SIGMA..DELTA. ADC) can be utilized in one of four configurations, as a subsampling bandpass receiver, a subsampling baseband receiver, a Nyquist sampling bandpass receiver, or a Nyquist sampling baseband receiver. For subsampling .SIGMA..DELTA. receivers, the sampling frequency i s less than twice the center frequency of the input signal into the .SIGMA..DELTA. ADC. For Nyquist sampling .SIGMA..DELTA. receivers, the sampling frequency i s at least twice the highest frequency of the input signal into the .SIGMA..DELTA. ADC. For baseband .SIGMA..DELTA. receivers, the center frequency of the outp ut signal from the .SIGMA..DELTA. ADC is approximately zero or DC. For bandpass .SIGMA..DELTA. receivers, the center frequency of the output signal from the .SIGMA..DELTA. ADC is greater than zero. The sampling frequency can be selected based on the bandwidth of the input signal to simplify the design of the digital circuits used to process the output samples from the .SIGMA..DELTA. ADC. Furthermore, the center frequency of the input signal can be selected based on the sampling frequency and the bandwidth of the input signal. The .SIGMA..DELTA. ADC within the receiver provides many benefits.
