    Abstract: The present disclosure proposes a micro power generation device including a plurality of generators stacked one above the other. Each of the plurality of generators includes: an upper electrode and a lower electrode spaced up and down; a spacer provided between peripheral edges of the upper electrode and the lower electrode; an upper friction material layer provided on a side of the upper electrode facing the lower electrode; and a lower friction material layer provided on a side of the lower electrode facing the upper electrode. The upper friction material layer, the lower friction material layer and the spacer together form a cavity. An intermediate spacer is provided between each adjacent two generators, each adjacent two generators and the intermediate spacer together form an intermediate cavity, and the intermediate cavity is filled with gas. A cavity of an upper one of any two adjacent generators communicates with the intermediate cavity between the two adjacent generators.

    Abstract: A signal generator includes N stages of cascaded control signal generating circuits, and is configured to receive K clock signals whose valid pulse edges are different from each other by a set time, an n-th control signal generating circuit of the N stages of control signal generating circuit generates a strobe signal based on a k-th clock signal of the K clock signals and sequentially outputs at least two different clock signals of other K−1 clock signals based on the strobe signal. A valid pulse edge of the k-th clock signal is within a valid pulse duration of a strobe signal of an (n−1)-th stage control signal generating circuit.
