ABSTRACT:
A charge pump having an output diode with a zero voltage drop. The present charge pump may be a multiple stage charge pump that may operate more efficiently than prior charge pumps by substantially removing the voltage drop across the output diode. The last stage in the charge pump receives a second input clock signal. The output diode includes a switch device coupled to a bootstrapping circuit which receives a third input clock signal and a fourth input clock signal. The third input clock signal and the fourth input clock signal are either non-overlapping high clock signals or non-overlapping low clock signals. A specified relationship between the second clock signal and the third clock signal, and a specified relationship between the third clock signal and the fourth clock signal are required to allow the bootstrapping circuit to properly augment the voltage passed through the switch device in the output diode.
