Abstract: A method of generating a transmission signal may include mixing a baseband signal assigned for transmission within a narrow frequency range (“assigned narrow frequency range”) included in a wireless communication channel to produce a shifted signal. The shifted signal may have a shifted frequency that is based on a shift from the assigned narrow frequency range toward a center frequency of the wireless communication channel by a frequency offset. The method may further include shifting a modulation frequency of a modulating signal toward the assigned narrow frequency range frequency range and away from the center frequency by the frequency offset. Additionally, the method may include mixing the shifted signal with the modulating signal to produce a transmission signal having a transmission frequency within the assigned narrow frequency range.

Abstract: A method of controlling a hybrid phase-locked loop may include generating a first control signal based on an offset signal and a second control signal and determining a difference between the first and the second control signals. The method may further include adjusting a value of the offset signal based on the difference between the first and the second control signals to drive a level of the first control signal to a level of the second control signal. The method may further include determining when the level of the first control signal crosses the level of the second control signal. After the level of the first control signal crosses the level of the second control signal, the method may include adjusting the value of the offset signal based on a number of occurrences of the level of the first control signal crossing the level of the second control signal.

Abstract: A circuit may include a digitally-controlled oscillator including a coarse frequency-tuning array with a multiple selectable coarse frequency-tuning segments. Each of the coarse frequency-tuning segments may have a coarse segment frequency step size. The digitally-controlled oscillator may also include a fine frequency-tuning array with multiple selectable fine frequency-tuning segments. The fine frequency-tuning array may have a fine array frequency step size that is at least twice the coarse segment frequency step size. The digitally-controlled oscillator may be configured to generate an output signal with a frequency based on the coarse frequency-tuning array and the fine frequency-tuning array.

Abstract: A circuit may include a phase detector configured to generate a phase error signal based on a feedback signal and an oscillator configured to generate an output signal. The feedback signal may be based on the output signal. The circuit may also include a determination unit configured to measure a phase of the feedback signal based on the phase error signal when an output of the phase detector and an input of the oscillator are communicatively decoupled. The circuit may also include an adjustment unit configured to subtract the measured phase of the feedback signal from an intermediate signal upon which the output signal is based when the output of the phase detector and the input of the oscillator are communicatively coupled.
