Abstract
A power supply boosting circuit provides increased pumping efficiency by driving the gate of a transistor in a first precharge circuit with the pumped output voltage from a second precharge circuit, thereby eliminating a threshold voltage drop from the output voltage of the first precharge circuit. The pumped output voltage from the first precharge circuit is then used to precharge a pumping node in a pumping circuit, which in turn, eliminates a threshold voltage drop from the output voltage of the pumping circuit. A transistor in the second precharge circuit can likewise be driven by the pumped output voltage from the first precharge circuit, further increasing the pumping efficiency.
