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.
Charge pump booster device comprising:
A method for saving energy in a charge pump booster device, having a charge pump circuit with an input terminal and an output terminal, and a load capacitor with a load node which is connected to the said output terminal;
A charge control circuit for a voltage booster having a charge pump circuit with an input terminal and with an output terminal coupled to a load node, the charge pump circuit having a plurality of switches coupled to one another in series between the input terminal and the output of the charge pump circuit and defining a plurality of circuit nodes between them, the charge pump circuit further having a plurality of storage capacitors, each storage capacitor having a first terminal coupled to a respective node, and a second terminal that receives phase signals, the charge control circuit comprising:
