Abstract

This paper presents a novel on-chip DC-DC voltage down converter (VDC): a temperature-independence reference voltage generator and a voltage-up converter. The architecture of the proposed VDC is simple, and can be fabricated by conventional CMOS technology. For 5 V to 3.3 V conversions, it provides an output voltage insusceptible to external supply-voltage bouncing, temperature variation, and load current variation. A temperature dependency of only 0.65 mV/°C and a voltage deviation within ±0.16% for ±10% variation of external supply voltage are achieved. The voltage is stabilized with ±17 mV for load current varying from 0 to 100 mA.
