    摘要: A voltage supply circuit and a method for controlling a voltage supply circuit are provided. The voltage supply circuit includes a positive charge pump stage that generates a positive voltage and a negative charge pump stage that generates a negative voltage. The voltage supply circuit also includes a control stage that compares a voltage representative of the negative voltage with a reference voltage and causes a slope of the positive voltage to decrease when the voltage representative of the negative voltage exceeds the reference voltage.

    摘要: An embodiment of a measuring circuit for measuring the leakage current flowing in a portion of an electronic device when said portion is biased by a biasing unit of the electronic device is proposed. The measuring circuit includes a first section configured to generate a threshold current, a second section configured to receive the leakage current, a third section configured to compare the threshold current with the leakage current, and a fourth section configured to generate an output voltage based on the comparison between the threshold current and the leakage current. Said first section is configured to set the value of said threshold current to a different value at each reiteration of an operating cycle. Said fourth section is configured to measure said leakage current based on a detection of a change in the value of the output voltage between two reiterations of the operating cycle.

    摘要: A voltage doubler circuit supports operation in a positive voltage boosting mode to positively boost voltage from a first node to a second node and operation in a negative voltage boosting mode to negatively boost voltage from the second node to the first node. The voltage doubler circuits receive two clock signals having different high voltage levels. A series of voltage doubler circuit are connected in a charge pump with controllable operation in the first and second modes. A connecting circuit interconnects the first and second nodes of the voltage doubler circuits to provide a first connection path, with a first input voltage, to support the positive voltage boosting mode operation and a second connection path, with a proper input voltage, to support the negative voltage boosting mode. A discharge circuit is provided to discharge the voltage doubler circuits when operation of the charge pump circuit is terminated.

    摘要: A cascode voltage generating circuit and method are provided. The circuit includes four switching elements. In a high voltage operation mode, the first and second switching elements, respectively, couple a first intermediate voltage input node to a first intermediate voltage output node, and a second intermediate voltage input node to a second intermediate voltage output node. In a low voltage operation mode, the third switching element couples the first and second intermediate voltage input nodes to a ground reference voltage level, and the fourth switching element couples the first and second intermediate voltage output nodes to a supply voltage level.
