By using bootstrapped technique, it can increase both of pump-efficiency and power-efficiency. The proposed bootstrapped based charge pump can avoid the threshold voltage drop in conventional Dickson charge pump circuits and enable them to generate a higher output voltage. Simulation by using HSpice level 3 model shows that for conventional Dickson charge pump, it convert the input low DC-voltage (Vin=1.5V) up to 3.8 times of it (VOUT=5.77V), the pump efficiency was 76.93%. Our work, however, can convert the low input DC-voltage (Vin=1.5V) up near to 4.8 times of it (VOUT=7.07V), the pump
efficiency can reaches up to 94.2%. The newly proposed bootstrapped based Dickson charge pump circuit is suitable for various low to high voltage applications for power saving.
