Abstract: Phase of an output signal is based on comparison of an oscillating signal with an adjustable threshold. Here, adjustment of the threshold results in a corresponding adjustment of the phase of the output signal. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal. In some aspects these phase adjustment techniques may be employed to provide one or more tunable multiphase clocks.

Abstract translation: 输出信号的相位基于振荡信号与可调阈值的比较。 这里，阈值的调整导致输出信号的相位的相应调整。 例如，可调阈值可以包括用于晶体管电路的可调偏置信号，由此将振荡信号提供给晶体管电路的输入，并且晶体管电路的输出提供输出信号。 在一些方面，可以采用这些相位调整技术来提供一个或多个可调多相时钟。
