In this thesis, the literature relating to charge pump dc-dc converters and their uses is reviewed. Charge pumps are useful in many circuits, including low-voltage circuits, dynamic random access memory circuits, switched-capacitor circuits, EEPROM's and transceivers. The important issues relating to charge pump design are power efficiency, output voltage ripple and area efficiency. This thesis describes the operation of three types of charge pump circuits. Power efficiency theory of charge pumps is discussed in detail. A method of estimating the output ripple of a charge pump from the size of the capacitors used is described. The optimal distribution of available capacitance for minimizing output ripple or maximizing power efficiency is derived. The tradeoffs between output ripple, power efficiency and total capacitance are discussed. The considerations involved in the design of charge pump circuits are described. A new charge pump circuit that uses two cascoded buffer transistors to improve the area efficiency is proposed. An implementation consisting of one of each of the three types of charge pumps was simulated for a 0.35-micron CMOS process. The simulation results verify the improved area efficiency of the double cascode charge pump.
