    摘要： The disclosure describes methods and apparatus for quickly prototyping of a solution developed using one or more sensing devices (e.g., sensors), functional blocks, algorithm libraries, and customized logic. The methods produce firmware executable by a processor (e.g., a microcontroller) on an embedded device such as a development board, expansion board, or the like. By performing these methods on the apparatus described, a user is able to create a function prototype without having deep knowledge of the particular sensing device or any particular programming language. Prototypes developed as described herein enable the user to rapidly test ideas and develop sensing device proofs-of-concept. The solutions produced by the methods and apparatus improve the functioning of the sensor being prototyped and the operation of the embedded device where the sensor is integrated.

    摘要： A circuit includes a current controller oscillator generating a CCO output signal at a CCO output, a charge pump boosting a supply voltage based on the CCO output signal and producing a charge pump output voltage at an output, and a current sensing circuit sensing load current at the output and generating a feedback signal having a magnitude that varies with the sensed load current if a magnitude of the sensed load current is between lower and upper load current thresholds. A frequency of the CCO output signal is constant at a lower frequency threshold where the sensed load current is below the lower load current threshold, asymptomically rises to an upper frequency threshold where the sensed load current is above the upper load current threshold, and is proportional to the feedback signal where the sensed load current is between the lower and upper load current thresholds.

    摘要： A charge pump circuit has load driven clock frequency management. The charge pump circuit includes a CCO generating a CCO output signal that has a frequency generally proportional to a feedback current, and a charge pump operated by the CCO output signal and boosting a supply voltage to produce a charge pump output voltage at an output coupled to a load. A current sensing circuit senses a load current drawn by the load and generates the feedback current as having a magnitude that varies as a function of the sensed load current if a magnitude of the load current is between a lower load current threshold and an upper load current threshold. The magnitude of the feedback current does not vary with the sensed load current if the magnitude of the sensed load current is not between the lower load current threshold and the upper load current threshold.
