Abstract: A current-bootstrap comparator includes a receiving unit, a first current generation unit and a second current generation unit. The receiving unit receives a load voltage signal, a low threshold voltage and a high threshold voltage. The first current generation unit generates a first current. The second current generation unit generates a second current having a magnitude substantially same as a magnitude of the first current and a direction reverse to the first current. The first current and the second current are supplied to a next-stage circuit as a source current and a corresponding sink current, respectively, when the level of the load voltage signal is higher than the high threshold voltage or lower than the low threshold voltage. The magnitudes of the first current and the second current substantially equal zero when the level of the load voltage signal is between the high threshold voltage and the low threshold voltage.

Abstract: A pre-charge circuit of a static random access memory (SRAM) controller and a pre-charging method thereof are provided. The pre-charge circuit of the SRAM controller includes a first switch, a second switch and a third switch. A first terminal of the first switch is coupled to a working voltage, a second terminal of the first switch is coupled to a first bit line of the SRAM controller, and the first switch is controlled by a first turn-on signal. A first terminal of the second switch is coupled to the working voltage, a second terminal of the second switch is coupled to a second bit line of the SRAM controller, and the second switch is controlled by a second turn-on signal. The third switch is coupled between the first bit line and the second bit line, and the third switch is controlled by a third turn-on signal. In a pre-charge mode, a time point at which the third switch is turned on is earlier than a time point at which the first switch is turned on and earlier than a time point at which the second switch is turned on.
