| Abstract(in English) | In this paper, design and evaluation results of a low-power voltage reference circuit with 1.0V output voltage by using a conventional CMOS process are reported. The objective of this study is to realize a voltage reference circuit with less than 1V of the output voltage for switching power supplies such as DC-DC converters. The circuit utilizes a MOS transistors in weakly inverted region, whose characteristic resembles to the one of a bipolar transistor, in order to obtain 1.0V stable output voltage that is independent of temperature. An actual chip was designed, fabricated, and evaluated by using a 0.6μm CMOS process. The evaluation result shows less than 0.38 % of output voltage variation when it is chosen 1.0V and the temperature changes from 0 ℃ to 75 ℃. The supply voltage for the entire circuit was 3.6V. The result demonstrates the effectiveness of using weakly inverted transistors in a voltage reference circuit. |
