    摘要： A method and a system for supplying power to a microcontroller with a single cell. One embodiment of the present invention discloses incorporation of a power supply pump circuit with the microcontroller and their dynamic interaction. The microcontroller sends its power requirements to the power supply pump circuit and in response, the power supply pump circuit controls the operating voltage with optimal efficiency. The dynamic update of power supply pump circuit results in an efficient use of the power supply pump circuit and thus results in a reduction of the number of dry cell batteries to only a single cell. Incorporation of the microcontroller and power supply pump circuit onto a single chip reduces the pin number requirements as well as the space required on the printed circuit board.

    摘要： The present invention relates to a band-gap reference circuit. The circuit comprises a plurality of diodes connected in series in one or more chains, a current source to flow current through the diode chains, and a selection of shunt current sources. The shunt current sources are connected in parallel with the main current sources and each, or any, can be selected in order to add current to the diode chain. In this manner, current flow through the diode chain is adjusted in order to provide a trimmable band-gap reference voltage. By adjusting the current flow, the high precision reference voltage circuit can provide a very accurate reference value for variations in process state, process error and temperature.

    摘要： A programmable system includes a programmable analog device including an operational amplifier to generate an output voltage based on input voltages at terminals of the operational amplifier. The programmable system also includes a system controller to direct the programmable analog device to reconfigure analog circuitry providing the input voltages to the operational amplifier. The reconfiguration of the analog circuitry allows the programmable analog device to implement discrete-time or continuous-time functions.

    摘要： A system includes a controllable voltage generator to generate a power supply voltage. The system also includes a system controller to determine a voltage level associated with the power supply voltage, and prompt the controllable voltage generator to generate the power supply voltage. The system includes a floating gate reference device to generate an absolute voltage reference based, at least in part, on the voltage level associated with the power supply voltage. The system can also include analog circuitry to perform one or more electrical operations responsive to the absolute voltage reference from the floating gate reference device.

    摘要： In one example, a chip includes integrated components configured to operate in the digital domain and the analog domain. An I/O pad located on the chip is configured to provide an external device access to the integrated components. A multifunction I/O interface cell between the I/O pad and the integrated components is configured to selectively connect different combinations of the components to the same I/O pad at different times. The multifunction I/O interface cell may include a first switching device connected to ground, a second switching device connected to a reference voltage, an analog input/output buffer, and a digital input/output buffer.
