摘要： Various embodiments are disclosed relating to a wireless transceiver. In an example embodiment, a method of compensating for phase imbalance and amplitude imbalance between corresponding in-phase signals and quadrature-phase signals includes providing a plurality of test tones of various frequencies to a receiver and determining, for each of the test tones, a respective phase imbalance and a respective amplitude imbalance between an in-phase (I) signal and a quadrature-phase (Q) signal of the test tone. The example method also includes determining a set of filter coefficients based on the determined phase and amplitude imbalances of the plurality of test tones and applying the set of filter coefficients to a plurality of filters. In the example method, a phase imbalance between an I signal and a Q signal of a received wireless signal is compensated for using a first filter of the plurality of filters. Further, an amplitude imbalance between the I and Q signals of the received wireless signal is compensated for using a second filter of the plurality of filters.

摘要： Various embodiments are disclosed relating to wireless systems, and relating to wireless transceivers. In an example embodiment, the wireless transceiver may include a voltage controlled oscillator (VCO) that may be controlled by a phase-locked loop (PLL). A fractional-N divider may be coupled to a feedback loop of the PLL and a delta-sigma modulator may control the fractional-N divider to vary the divider number of the fractional-N divider to cause the VCO to output a modulated frequency spectrum. In another embodiment, modulation path calibration may be performed by inputting an amplitude and phase modulated transmit spectrum to the transceiver's receiver to be demodulated. The demodulated transmit spectrum may then be analyzed to determine if the transmit spectrum meets one or more signal requirements, such as falling within a required spectral mask. The AM path delay and/or the PM path delay of the transmitter may be adjusted to decrease a mismatch in timing or delay between the AM and PM paths.

摘要： A loop filter for use in a frequency synthesizer provides improved spurious performance using switched capacitors. The loop filter includes a first switched capacitor having a first capacitance value and which is operable to charge to a first voltage corresponding to a current pulse indicative of a difference in phase or frequency between a reference signal and a feedback signal. The loop filter further includes a second switched capacitor having a second capacitance value and which is operable to charge to a second voltage from the first voltage and produce a control voltage based upon the second voltage. The loop filter has a bandwidth determined by a ratio of the second capacitance value to the first capacitance value.

摘要： A radio transmitter within a transceiver includes a digital processor and analog circuitry for modulating and transmitting an outgoing digital signal in multiple modes of operation. The digital processor digitally modulates the outgoing digital signal to produce one of a constant envelope modulated digital signal and a variable envelope modulated digital signal based on the particular modulation scheme being used to modulate the outgoing digital signal. In addition, the digital processor filters the outgoing digital signal using filter values selected based on the signal bandwidth of the outgoing digital signal. The analog circuitry converts digital envelope and phase signals of the modulated digital signal to analog envelope and phase signals, and up-converts the analog phase signal from an IF signal to an RF signal, using a loop filter that is programmable based on the signal bandwidth of the outgoing digital signal.

摘要： An integrated circuit radio frequency (RF) transmitter includes a phase locked loop having a multi-mode loop filter that is operable to provide wide band response with a fast settle time in a startup mode of operation and a relatively more narrow response with a longer settle time but with improved filtering in a steady state mode of operation according to one embodiment of the invention. The multi-mode loop filter includes, in one embodiment, selectable resistance circuitry for selecting between a plurality of resistance values based upon a two-state multi-mode control signal to provide the selected resistance values and selectable capacitance circuitry for selecting between a plurality of capacitance values based upon the two-state multi-mode control signal and for operatively coupling selected capacitors to selected resistors to provide the selected capacitance values. As a further aspect of the embodiment of the present invention, the multi-mode loop filter includes buffers for charging non-selected capacitors while not operationally coupled to the multi-mode loop filter to avoid additional settle time for the circuitry.

摘要： The invention relates to a method of manufacturing a product having a sub-micron primary particle such as metal oxide, metal oxidhydroxide or metal hydroxide product, said method comprising the steps of: introducing a solid reactor filling material in a reactor, introducing a metal-containing precursor in said reactor, introducing a co-solvent into the said reactor, introducing a supercritical solvent in the said reactor. By these steps a contact between the metal-containing precursor and the co-solvent is established, thus resulting in the formation of said product in the proximity of the said solid reactor filling material. The present invention offers the astonishing possibility of producing anatase phase of TiO2 at temperatures as low as between 50° C. and 100° C. and at concurrent pressures of 100-200 bar. The invention also relates to a product such as anatase TiO2 produced by the method and also relates to an apparatus utilising the method.
