摘要： A method (1300) includes demodulating phase contamination in an input signal to generate a baseband signal ( 1306). The method also includes modulating the input signal based on the baseband signal to generate an output signal which has less phase contamination than the input signal (1308). The phase contamination may be demodulated using a phase demodulator or a frequency modulation (FM) detector. A portion of the input signal may be down-converted to a lower frequency, and the phase contamination in the down-converted portion of the input signal may be demodulated. Additional phase contamination in the output signal may be demodulated and used to regulate a level of the baseband signal used during modulation of the input signal (1312). The output signal may have less phase noise or period jitter than the input signal.

摘要： Circuit and method for generating a signal for use in locking a second signal on a first signal. The first and second signals have an associated frequency. A first beat note signal (PD1) and a second beat note signal (PD2) are generated from the first and second signals, respectively, when the frequencies of the first and second signals are not equal. The circuit includes a first and second flip-flop and detector circuitry. The first flip-flop (502) is configured to receive the first and second beat note signals for generating a first state signal (S0). The first flip-flop (502) generates the first state signal (S0) by sampling the second beat note signal (PD1) at a first periodic interval of the first beat note signal. The second flip-flop (504) is configured to receive the first and second beat note signals for generating a second state signal (S1). The second flip-flop (504) generates the second state signal (S1) by sampling the second beat note signal at a second periodic interval of the first beat note signal (PD1). The detector circuitry (506, 508) is coupled to receive the first and second state signals from the first and second flip-flops for detecting a polarity of the frequency difference between the first and second signals. The polarity of the frequency difference is defined in a tri-state having a positive state, a negative state, and a zero state.

摘要： A propagating signal transmitted through a propagating medium is received where a detected disturbance to a signal property of the propagating signal is analyzed to detect whether a touch input has been provided. It is determined whether the detected disturbance matches a signature and in the event it is determined that the detected disturbance matches the signature, it is determined that the detected disturbance does not correspond to the touch input.

摘要： Serial data transfer uses ever increasing transmission rates. The data transfer rate of a clock-and-data recovery (CDR) deserializer can be increased by using multiple independent sampler blocks that process serial input data in parallel. For this purpose, the clock output signals from the various independent blocks are first mutually aligned in proper order using a lower speed clock, and subsequently offset from one another such that sampling instances of the various sampler blocks are interleaved. Digitized data words corresponding to common input data and outputted by the various sampler blocks are compared after alignment of the clock output signals to correct additional timing misalignment between the multiple sampler blocks. The digitized data words need only be aligned once or at most infrequently after the clock output signals are aligned, since the additional timing misalignment is caused mainly path delays that are substantially invariant over time.
摘要翻译：串行数据传输使用不断增长的传输速率。通过使用并行处理串行输入数据的多个独立采样器模块，可以提高时钟和数据恢复（CDR）解串器的数据传输速率。为此，来自各个独立块的时钟输出信号首先使用较低速度的时钟以适当的顺序相互对齐，并且随后相互偏移，使得各个采样器块的采样实例被交错。在对齐时钟输出信号之后比较与由公共输入数据并由各个采样器块输出的数字化的数据字，以校正多个采样器块之间的附加的时序未对准。在时钟输出信号对齐之后，数字化的数据字只需要对准一次或者最多不多次，因为附加的时序未对准主要是由于随时间推移基本上不变的路径延迟引起的。

摘要： An improved frequency synthesizer (100) capable of producing true DC frequency modulation without the need to DC frequency modulate the reference oscillator. The synthesizer (100) includes a phase comparator (104) which compares the reference signal (102) and the feedback signal (112). The output of said phase comparator (104) is filtered and coupled to the main VCO (108). A balanced image mixer (200) mixes the two signals from the main VCO (108) and an offset VCO (300). The offset VCO (300) is a low frequency (e.g. 100 to 300 KHz) integrated offset VCO (308) whose center frequency is controlled accurately, by means of matching to a VCO (306) which is controlled by a feedback loop, and by using an image balanced mixer (200) to reduce the image response to substantially reduce or eliminate the filtering required at the mixer output. The configuration of the offset mixer within the synthesizer loop, any residual spurious content due to imperfect image balance or carrier feedthrough of the mixer is attenuated by the loop response. The output signal of the mixer (200) is looped back to the phase comparator (104) after being divided by N through a divider (114).
