摘要： Disclosed are systems, devices, circuits, components, mechanisms, and processes in which a switching mechanism can be coupled between components. The switching mechanism is configured to have an on state or an off state, where the on state allows current to pass along a current path. A monitoring mechanism has one or more sensing inputs coupled to sense an electrical characteristic at the current path. The electrical characteristic can be a current, voltage, and/or power by way of example. The monitoring mechanism is configured to output a reporting signal indicating the sensed electrical characteristic. The monitoring mechanism can be integrated with the switching mechanism on a chip.

摘要： Methods, apparatus and systems for controlling a photovoltaic panel, to output three-phase power while ensuring the power source operates safely include determining a temperature of the photovoltaic panel, determining a voltage provided from the photovoltaic panel, determining a parameter based on the voltage and the temperature and controlling a DC to three-phase power converter based on the determined parameter. The three-phase power converter may be a pulse amplitude modulated current converter (PAMCC), configured to output first, second and third pulse amplitude modulated current pulse from three terminals controlled in timing and phase so that when respective outputs of multiple PAMCCs are connected, each phase of the plurality of PAMCCs is demodulated to produce a three-phase alternating current output. The PAMCC may be controlled through tables of pulse durations based on the determined parameter. The voltage output may be controlled through a fast control loop and through a slower control loop.

摘要： A system and method of creating a highly efficient digital amplifier which can take either analog or digital inputs, and produce a high power accurate representation of the input to drive speakers or other low impedance load is described. The system employs a transition detector and delay unit which allows the comparator of the signal modulator to ignore its inputs for a pre-determined number of subsequent clock cycles once an output transition has been detected. Through the use of faster clocks and variable clock cycle skips upon the comparator's output transition, finer resolution of the feedback's clock period for noise-shaping purposes is achieved. Finer resolution of the clock period allows the present invention to employ a more aggressive noise-shaping than previously possible.In another aspect of the invention; additional delta-sigma modulator noise suppression is obtained by using the common bridge implementation of the power output stage with the improvement of configuring the bridge to create a 3-state condition instead of the conventional 2 states. By controlling the two halves of the bridge independently of one another, an output with 3 states makes for improved noise shaping performance.

摘要： Methods and devices are disclosed for performing analog to digital signal conversion in shorter time and/or with less power consumption than that of a comparable analog to digital conversion that uses a conventional sequential approximation method based on a binary search. In one embodiment, a predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. A comparison is made between the analog guess signal and a received, analog input sample signal. The result of the comparison is used to improve on the initially supplied guess in a next cycle. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal. In one embodiment, a digital modeler is used to model a process underlying the analog input sample signal and to thereby provide fairly good guesses.

摘要： A method and apparatus for an ultra-high sensitivity, low cost, passive (no battery) low-power energy harvesting data transmitting circuit energy, such as a RFID (Radio Frequency IDentification) tag integrated circuit “chip.” By using combinations of special purpose design enhancements, the low-power energy harvesting passive data transmitting circuit, such as the RFID tag chip, operates in the sub-microwatt power range. The chip power should be derived from a low-microwatt per square centimeter RF field radiated to the RFID tag antenna from the tag reader (interrogator) or derived from a suitable low signal source, such as a sonic transducer (e.g., a piezoelectric transducer or a low level DC source, such as a bimetallic or chemical source).
