一个新奇 Schmitt 扳机电路,由一个重设集合(RS ) 实现了扳机并且二简单不同转换 ers,被建议。它的扳机层次被二互补 Metal-Oxide-Semiconductor (互补金属氧化物半导体) 决定转换 ers。对比与传统六个晶体管 Schmitt 扳机,它的温度和供应电压特征被分析了。这二个扳机被使用进松驰振荡器,结果证明在这篇论文的建议的那在宽温度范围上有更好的性能,其从 0 ~ 85 deg C 的温度系数是传统的 1/5。
A novel Schmitt trigger circuit, implemented by a reset-set (RS) trigger and two simple distinct inverters, is proposed. Its trigger levels are determined by two Complementary Metal- Oxide-Semiconductor (CMOS) inverters. Contrast with traditional six transistors Schmitt trigger, its temperature and supply voltage characteristics have been analyzed. These two triggers are applied into relaxation oscillator and the result shows that the proposed one in this paper has better performance over wide temperature range, whose temperature coefficient from 0 to 85℃ is 1/5 of the traditional one.
