چکیده
Charge pump circuits are used to obtaining higher voltages than normal power supply voltages in low voltage Phase Lock Loop (PLL), flash Memories & DRAM’s. New integrated Dickson Charge pump design with charge transfer switches (CTS’s) is optimized and compared including the losses due to devices parasitic is described. Results show that the CTS based Dickson charge pump is the best structure for integration. Therefore, techniques to improve performance and conversion efficiency of integrated Dickson Charge pump are proposed. A prototype of the integrated Charge pump was fabricated in a 0.18-μm CMOS process with the proposed techniques. Measured results have been presented, demonstrating the improvements in performance and conversion efficiency.
