    Abstract: Exemplary embodiments are directed to devices and method for operating a charge pump. A method may include activating a first switch coupled between a capacitor and a ground voltage over a first period of a charging phase. The first period may coincide with a non-overlapping time between the charging phase and an output phase. The method may also include activating a second switch coupled between the capacitor and an input voltage over a second period of the charging phase, wherein the first period begins prior to the second period. Further, the method may include deactivating the second switch over a third period of the charging phase and deactivating the first switch over a fourth period of the charging phase, wherein the third period begins prior to the fourth period.

    Abstract: Control circuits for generating output enable signals are disclosed. In one aspect, a control circuit is provided that employs combinatorial logic to generate an output enable signal that meets timing constraints using a standard clock signal, a feedback clock signal based on the standard clock signal, and a single data rate (SDR) data output stream. The control circuit includes a double data rate (DDR) conversion circuit configured to generate a DDR output stream based on a received SDR output stream. The control circuit includes an output enable circuit configured to receive the standard clock signal, feedback clock signal, and DDR output stream, and to generate the output enable signal that is asserted and de-asserted according to the defined timing constraints. The control circuit is configured to generate an accurately timed output enable signal without the need for a fast clock signal in addition to the standard clock signal.
