ABSTRACT:
A charge pump circuit including an input rail, an output rail, a voltage rail, a control line, an MOS input transistor including a gate and a channel connected between the input rail and the voltage rail, and an MOS output transistor including a gate and a channel connected between the output rail and the voltage rail. The gate of the input transistor is connected to the gate of the output transistor and a switch connects the channel of the output transistor to the voltage rail in response to a signal on the control line. The channel of an input cascode transistor connects the channel of the input transistor to the input rail and the channel of an output cascode transistor connects the channel of the output transistor to the output rail. The gate of the input cascode transistor is connected to the gate of the output cascode transistor.
