An on-chip differential-amplifier-based DC-to-DC voltage down converter (VDC) is proposed. The converter is a negative feedback-type voltage follower with precise internal reference voltage generator and high current drive capability. VDC converts 5 V to lower voltage so that the internal circuits of the chip are used. In this paper, 3 V is used as a test vehicle. The proposed VDC has characteristics such as output voltage remains 3 V over a large load current range (0-100 mA) and temperature dependency of 3.2 mV/°C. The VDC chip was fabricated in a 0.8 μm single-poly-double-metal CMOS process and layout size is 690×210 μm2. The output voltage is stabilized within ±2.8% for supply voltage with ±10% variation achieved
