Abstract:
A pump circuit comprising: a plurality of switching elements connected in series between a first node to which a first voltage is applied and an output node from which a second voltage other than the first voltage is output;a plurality of capacitors, each of which having a first terminal and a second terminal, the first terminal of each capacitor being connected to a respective connection node of the plurality of switching elements;a signal generator connected to the second terminal of the capacitors, for generating a driving signal when a control signal is a first logic and stopping generation of the driving signal when the control signal is a second logic;a reset circuit connected to at least one of the connection nodes, for resetting a voltage of the at least one connection node to a third voltage other than the second voltage when the control signal changes from the second logic to the first logic; andwherein the third voltage is a voltage between the first voltage and the second voltage.
