摘要： A system provides closed-loop gain control in a WCDMA mode and open loop control in an EDGE/GSM mode. Gain control is distributed across analog devices and a digital scaler in a wireless receiver. In the WCDMA mode, a loop filter generates an error signal that is forwarded to analog and digital control paths. The analog control path includes a first adder, a programmable hysteresis element, and a lookup table. The analog control signal is responsive to thresholds, which when used in conjunction with a previous gain value determine a new gain value. The digital control path includes a second adder, a programmable delay element, and a converter. A control word is responsive to a difference of the error signal, a calibration value, and the analog control signal. Blocker detection is provided in the WCDMA mode of operation. A controller sets system parameters using a state machine.

摘要： A controller and a circuit work together to enable a selective and dynamic adjustment to correct phase and gain imbalances in quadrature signal paths of a receiver. Under select conditions, it has been determined that statistical estimates of gain and phase imbalance can be applied to adjust signals in the quadrature signal paths of a receiver. The controller validates the select conditions before updating the estimate of the gain imbalance and the estimate of the phase imbalance. The controller directs a compensator under select operating conditions such that validated dynamic estimates of the gain and phase imbalance or calibration data is applied to the quadrature signal paths. The controller disables the compensator and enables an estimator and a calculator when estimates are unavailable for the present operating conditions.

摘要： A method and apparatus is disclosed for voltage-controlled oscillator selection in a multi-mode system having multiple voltage-controlled oscillators. Part of oscillator selection is a calibration operation that utilizes maximum and minimum capacitance limits for a voltage-controlled oscillator, which translates to a frequency range, to calculate overlap regions. Overlap regions comprise frequency ranges that overlap such that the overlap region may be generated by two voltage-controlled oscillators with adjacent frequency ranges. One voltage-controlled oscillator selection routine comprises a real time voltage-controlled oscillator calibration and selection routine that executes every time the system requests a new frequency. Another selection routine comprises a start-up routine that executes only at power up or periodically. Another selection routine comprises a successive voltage-controlled oscillator routine that executes every time a frequency is requested by comparing a requested frequency to different frequency thresholds without executing a calibration operation.

摘要： A serial peripheral interface (SPI) controller can be configured in response to data received via the interface. The SPI controller can perform read and write operations upon registers of a register bank in response to signals received via one or more of a data signal line, a clock signal line, and a select signal line. By detecting combinations of signals on one or more of the data signal line, clock signal line and select signal line, the SPI controller can detect the initiation of data read and write operations that may be in accordance with any of several different SPI protocols.

摘要： Apparatus and methods for adjusting a gain of an electronic oscillator, such as a voltage-controlled oscillator (VCO), are disclosed. In one aspect, an apparatus for compensating for VCO gain variations includes a charge pump controller. The charge pump controller can be configured to select a VCO gain model based on a comparison of a VCO gain indicator and a threshold value stored in a memory, obtain VCO gain model parameters from the memory corresponding to the selected VCO gain model, and compute a charge pump current control value using the VCO gain model parameters. The charge pump current control value can be used to compensate for VCO gain variations.
