摘要： Aspects of the disclosure are directed to communications between respective power domains (circuitry) that may operate in a stacked arrangement in which the each domain operates over a different voltage range. A first circuit provides differential outputs that vary between first and second voltage levels, based on transitions of an input signal received from a first one of the power domains. First and second driver circuits are respectively coupled to the first and second differential outputs. A third driver circuit operates with the first and second circuits to level-shift the input signal from the first power domain to an output signal on a second power domain by driving an output circuit at the second voltage level in response to the input signal being at the first voltage level, and driving the output circuit at a third voltage level in response to the input signal being at the second voltage level.

摘要： Aspects of this disclosure are directed to level-shifting approaches with communications between respective circuits. As may be implemented in accordance with one or more embodiments characterized herein, a voltage level of communications passed between respective circuits are selectively shifted. Where the respective circuits operate under respective power domains that are shifted in voltage range relative to one another, the voltage level of the communications is shifted. This approach may, for example, facilitate power-savings for stacked circuits in which a low-level voltage of one circuit is provided as a high-level voltage for another circuit. When the respective circuits operate under a common power domain, the communications are passed directly between the respective circuits (e.g., bypassing any level-shifting, and facilitating fast communication).

摘要翻译：本公开的方面涉及通过各个电路之间的通信的电平转换方法。如可以根据本文特征的一个或多个实施例来实现的，在各个电路之间通过的通信的电压电平被选择性地移位。在各个电路在相对于彼此在电压范围内移位的相应功率域下工作时，通信的电压电平发生偏移。例如，该方法可以有助于对于其中提供一个电路的低电平电压作为另一个电路的高电平电压的堆叠电路的功率节省。当各个电路在公共功率域下工作时，通信直接在相应的电路之间传递（例如，绕过任何电平转换，并促进快速通信）。
