摘要： Generally, displays, like liquid crystal displays (LCDs), use a DC-free addressing voltage in order to prevent decomposition of the display. Here, an integrated circuit (IC) is provided that compensates for temperature dependencies. This IC typically uses a thermistor or temperature varying element to measure the temperature of the display and adjusts the common reference voltage in response to the measured temperature.

摘要： A rectifier circuit for use in an energy harvesting application in which mechanical energy is converted into electrical energy by using an AC generator using an active rectifier bridge with a pair of input terminals adapted to be connected to an output of the AC generator and a pair of output terminals, an inductor connected across the output terminals of the active rectifier bridge and a storage capacitor. A pair of output switches selectively connects the storage capacitor across the inductor. A controller controls the active rectifier bridge and the pair of output switches such that in successive switching cycles within any half wave of AC input voltage from the output of the AC generator the inductor is first loaded by current from the output of the AC generator and then discharged into the storage capacitor. An energy harvesting system which uses an AC generator for generating electrical energy out of mechanical energy, a rectifier circuit which is connected with the input to the output of the AC generator and a low power wireless system as application unit. A method of rectifying an AC output voltage of an AC generator for use in an energy harvesting application.

摘要： A step-up DC voltage converters circuit and method of operation which overcomes the problems associated with the prior art skip mode converters by reversing the flow of energy in the step-up DC voltage converter at the end of each switching cycle for a short constant time duration, thus making it possible to operate the step-up DC voltage converter over the full load current range at a fixed frequency which substantially facilitates filtering the output voltage. In addition to this the peak-to-peak output voltage ripple is less as compared to that of skip mode converters.

摘要： An unregulated inductorless direct current to direct current converter comprising a first voltage-to-current converter configured to convert a first voltage to a first current and a second voltage-to-current converter configured to convert a second voltage to a second current. A regulation circuit is coupled to the first and second voltage-to-current converters and configured to generate an output current proportional to the difference between the first and second currents. Also a variable frequency oscillator is coupled to the regulation circuit, the oscillator receiving as a control current the output current therefrom and outputting a clock signal having a frequency proportionate to the control current. The converter further comprises an output stage coupled to receive the clock signal and receiving an input voltage and outputting an output voltage, the output voltage and the input voltage having a ratio that is determined by the clock signal.
