摘要： A wireless receiver (100) for receiving and demodulating a frequency modulated RF (radio frequency) signal by a direct conversion procedure, including channels (110, 112) for producing in-phase and quadrature components of a received RF signal, and a processor (123, 133) for periodically estimating an error in at least one of the in-phase and quadrature phase components and for producing a signal for adjustment of at least one of the in-phase and quadrature components to compensate for the detected error, wherein the processor is operable to apply alternatively each of a plurality of different procedures to estimate the error, the procedures including a first procedure which is applied when a signal quality value of the received RF signal is above a threshold value and a second procedure which is applied when a signal quality value of the RF received signal is not above the threshold value.

摘要： A wireless communication unit (100) comprises a voltage controlled oscillator (123) having an active device (450) operably coupled to a first variable capacitance (425) to provide a variable capacitance value based on an applied steering line voltage, and a feedback network comprising a resonator (475), operably coupled to an output of the active device, for feeding power back to an input of the active device to sustain oscillations (123). Notably, a second variable capacitance is operably coupled to receive a control voltage from the steering line (405) and located between the resonator (475) and the active device (450).
