Abstract
A charge pump circuit comprises a plurality of subcircuits, where the subcircuits are connected to each other in a single or a dual array having a repeating pattern. Each of the subcircuits comprises one or more of the following: an X-channel device having an X-gate terminal, an X-source terminal and an X-drain terminal, a Y-channel device having a Y-gate terminal, a Y-source terminal and a Y-drain terminal, and a capacitor; wherein a first end of the capacitor, the X-drain terminal, and the Y-drain terminal are connected with each other to form the common drain terminal; and wherein a second end of the capacitor is the clock terminal.
