The charge pump CMOS circuit designs are presented for bio-medical applications wherein the clock voltage is boosted internally. Four and six-stage charge pumps are implemented in 1.5 μm n-well CMOS process. The charge pump circuits can be operated in 1.2 V - 3 V power supply voltage range. Outputs of 12.5 V and 17.8 V are measured from four and six-stage charge pumps, respectively with a 3 V power supply. The charge pump circuits can also be used to generate clock voltage higher than the input clock voltage. In the present design, the clock voltages, 8 V and 11 V have been generated from four-stage and six-stage charge pumps. respectively which are nearly 2.5 and 4 times the input clock voltage of 3 V. The technique of boosting the clock internally has been applied in implementation of a bio-implantable battery powered electrical stimulation chip.
