摘要： Methods and apparatuses featuring a multiplying injection- locked oscillator are described. Some embodiments include a pulse-generator-and-injector and one or more injection- locked oscillators. The outputs of the pulse-generator-and-injector can be injected into corresponding injection points of an injection- locked oscillator. In embodiments that include multiple injection- locked oscillators, the outputs of each injection-locked oscillator can be injected into the corresponding injection points of the next injection- locked oscillator. Some embodiments reduce deterministic jitter by dynamically modifying the loop length of an injection- locked oscillator, and/or by using a duty cycle corrector, and/or by multiplexing/blending the outputs from multiple delay elements of an injection-locked oscillator.

摘要： A local oscillator communicates a signal of relatively low frequency across an integrated circuit to the location of a mixer. Near the mixer, a frequency-multiplying SubHarmonically Injection-Locked Oscillator (SHILO) receives the signal and generates therefrom a higher frequency signal. If the SHILO outputs I and Q quadrature signals, then the I and Q signals drive the mixer. If the SHILO does not generate quadrature signals, then a quadrature generating circuit receives the SHILO output signal and generates therefrom I and Q signals that drive the mixer. In one advantageous aspect, the frequency of the signal communicated over distance from the local oscillator to the SHILO is lower than the frequency of the I and Q signals that drive the mixer locally. Reducing the frequency of the signal communicated over distance can reduce power consumption of the LO signal distribution system by more than fifty percent as compared to conventional systems.
摘要翻译：本地振荡器将跨越集成电路的相对较低频率的信号传送到混频器的位置。在混频器附近，倍频次谐波注入锁定振荡器（SHILO）接收信号并从中产生较高频率的信号。如果SHILO输出I和Q正交信号，则I和Q信号驱动混频器。如果SHILO不产生正交信号，则正交发生电路接收SHILO输出信号并从其产生驱动混频器的I和Q信号。在一个有利的方面，从本地振荡器到SHILO的距离传递的信号的频率低于驱动混频器的本地I和Q信号的频率。与常规系统相比，降低信号传输距离的频率可以将LO信号分配系统的功耗降低50％以上。

摘要： An integrator (100) comprises an amplification and phase shifting element (170) with a feedback path (130) forming a loop and comprising a capacitive element (140). An input signal is summed into the loop, and the loop is arranged to oscillate at an oscillation frequency higher than the frequencies of interest in the input signal. The loop includes a filter (160) for attenuating the oscillation signal to ensure that the amplification and phase shifting element (170) can provide amplification for the input signal. The input signal is integrated and the integrated signal perturbs the zero crossings of the oscillation signal.

摘要： A method of synchronising a local oscillator signal with a main oscillator signal in a network, wherein the local oscillator signal has a phase shift relative to and upon appearance of the main oscillator signal, which phase shift is being used as an at least initially fixed reference phase shift between the thus synchronised local oscillator signal and the main oscillator signal. Synchronisation accompanied by sudden phase jumps is thus avoided.
