Charge pump circuit generates the DC voltages which are higher than the normal power supply Voltage Drain Drain (VDD) or lower than the GrouND voltage (GND). In this paper, an on chip high voltage generator with bulk CMOS process using polysilicon diodes is presented. As the polysilicon diodes are completely isolated from the bulk so the output voltage is not limited by the junction breakdown voltage of CMOS in charge pump circuit. The output voltage of voltage generator realized by this technique is much higher than n well/p well substrate breakdown voltage with standard CMOS process.
