This paper proposes a new on-chip voltage down converter(VDC), which employs a new reference voltage generator(RVG). The converter adopts a temperature-independence reference voltage generator, and a voltage-up converter. The architecture of the proposed VDC has a high-precision, and it was verified based on a 0.25 1P5M standard CMOS technology. For 2.5V to 1.0V conversion, the RVG circuit has a good characteristics such as temperature dependency of only 0.2mV/, and the voltage-up circuit has a good voltage deviation within ± 0.12% for ± 5% variation of supply voltage VDD. The output voltage is stabilized with ± 1mV for load current varying from 0 to 100mA.
