Abstract: The load pump booster device with transfer and recovery of the charge including a charge pump circuit with an output terminal connected to a load capacitor by means of a load node. In turn, the charge pump circuit includes a plurality of transfer transistors connected to one another in series, and define a plurality of transfer nodes. Each transfer node is connected to a storage capacitor. The booster device also includes a plurality of controlled switches interposed between the load node and a respective transfer node, in order to connect to the load node a single one of the transfer nodes. By this means, between the load capacitor and the storage capacitors there takes place a phase of transfer of charge followed by a phase of recovery of charge, from the storage capacitors to the load capacitor.

Abstract: Presented is an energy efficient charge pump, that includes at least two stages. Each stage has input and output nodes, which correspond to terminals of a first transistor. A boost capacitor is tied to the input node, and a second capacitor is tied to an internal node, which is also the gate terminal of the first transistor. A second transistor is located between the input node and the internal node, and has a gate coupled to the output node. A driving signal generator generates ramped voltage driving signals and non-ramped voltage driving signals. Attached to the driving signal generator is a phase driver that applies the ramped voltage driving signals to the boost capacitor and applies the non-ramped voltage driving signals to the second capacitor. Also presented also is method of driving a charge pump, such as the one described above, where the boost capacitor is driven with a ramped voltage signal, while the second capacitor is driven with a non-ramped voltage signal.

Abstract: The high-voltage bidirectional switch includes a controlled transistor having a first terminal and a second terminal set, respectively, at a first potential and at a second potential. The controlled transistor moreover includes a control terminal connected to a control block, which is in turn connected to a precharge block The controlled transistor has its bulk region connected to a biasing block which is in turn connected both to the precharge block and to the second terminal of the controlled transistor. The control block and the biasing block are moreover connected to a signal-generator block connected to a control unit.
