摘要： Improvements in the efficiency of two charge pump designs are presented. As a charge pump switches between modes, capacitances are charged. Due to charge sharing between capacitances, inefficiencies are introduced. Techniques for reducing these inefficiencies are presented for two different charge pump designs are presented. For a clock voltage doubler type of pump, a four phase clock scheme is introduced to pre-charge the output nodes of the pump's legs. For a pump design where a set of capacitances are connected in series to supply the output during the charging phase, one or more pre-charging phases are introduced after the reset phase, but before the charging phase. In this pre-charge phase, the bottom plate of a capacitor is set to the high voltage level prior to being connected to the top plate of the preceding capacitor in the series.

摘要： A high voltage switch is presented that, rather than relying upon a charge pump to boost the voltage applied to the switches gate in order to compensate for the switch's threshold voltage, a combination of high voltage devices to eliminate the threshold voltage from the switch. This will save on the needed circuit area and reduce the current and, consequently, power consumption. In the exemplary embodiment, the switch circuit passes an input voltage from an input node to an output node in response to an enable signal. The switch includes a level shifter connected to the input node and is connected to receive the enable signal to provide the input voltage as output when the enable signal is asserted. The circuit also includes a first depletion type NMOS transistor that is connected between the input node and a first intermediate node and having a gate connected to receive the output of the level shifter, and a PMOS transistor that is connected between the first intermediate node and the output node and having a gate connected to receive an inverted form of the enable signal.

摘要： A level shifter circuit suitable for high voltage applications with shoot-through current isolation is presented. The level shifter receives a first enable signal and receives an input voltage at a first node and supplies an output voltage at a second node. The circuit provides the output voltage from the input voltage in response to the first enable signal being asserted and sets the output node to a low voltage value when the first enable signal is de-asserted. The level shifting circuit includes a depletion type NMOS transistor, having a gate connected to the output node, and a PMOS transistor, having a gate connected to the first enable signal. It also includes a first resistive element that is distinct from the NMOS and PMOS transistors. The NMOS transistor, the PMOS transistor and the first resistive elements are connected in series between the first and second nodes, with the NMOS transistor being connected to the first node. The level shifter further includes a discharge circuit connected to the second node and to receive a second enable signal. The second enable signal is asserted when the first enable signal is de-asserted and is asserted when the first enable signal is de-asserted, and the discharge circuit connects the second node to the low voltage value when the second enable signal is asserted and isolates the second node from ground when the second enable signal is de-asserted.

摘要： A charge pump system using a current based regulation method, in addition to the typical voltage based regulation methods is presented. The current flow in the charge pump is determined independently of the output voltage. By sensing the current going through the charge pump while its output is being regulated to the target level, the strength of charge pump can be dynamically adjusted in term of regulation level, branch assignment, clock frequency, clock amplitude, and so on. Indirectly sensing the current going through pump (not in serial with output stage to allow additional IR drop) will allow the pumps to have matrix of V and I to better adjust the charge pump parameters for current saving and ripple reduction.
