摘要

本研究提出一种利用开关电容技术的无电阻带隙电压参考电路，具有宽温度范围、低电源电压和最小功耗的特点。它具有一个自引导时钟升压器，提高了升压效率，减少了泄漏功率，从而延长了工作温度范围。引入了PTAT-CTAT电压发生器来最小化有源面积，以及基于高性能开关的分压器来提高温度系数。开关电容电路用于产生参考电压。在0.45 V标称电压下，采用65 nm标准CMOS技术对所提出的电路进行了仿真。该电路在−50°C至150°C范围内的温度系数为38 ppm/°C，功耗为22.77 nW，线灵敏度为0.72%，硅面积为0.009 mm²。

A 0.45-V supply, 22.77-nW resistor-less switched-capacitor bandgap voltage reference

This research presents a resistor-less bandgap voltage reference circuit utilizing switched-capacitor technology, designed for a wide temperature range, low supply voltage, and minimal power consumption. It features a bootstrapped clock booster that improves boosting efficiency and reduces leakage power, thereby extending the operational temperature range. A PTAT–CTAT voltage generator is introduced to minimize the active area, along with voltage dividers based on high-performance switches to enhance the temperature coefficient. A switched-capacitor circuit is used to generate the reference voltage. The proposed circuit is simulated in a 65 nm standard CMOS technology at a nominal voltage of 0.45 V. The circuit achieves a temperature coefficient of 38 ppm/°C from −50 °C to 150 °C, with a power consumption of 22.77 nW, a line sensitivity of 0.72 %, and a silicon area of 0.009 mm².

期刊介绍： The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency. Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
