The Stihl MS 462 C-M and MS 462 R C-M chain saws were specially engineered for the professional user who desires more power and reduced weight, resulting in less user fatigue. Both chain saw models feature an excellent power-to-weight ratio. These chain saws feature the next generation of...
测量匀变速直线运动的加速度的实验装置A为滑块滑块上的遮光板测量匀变速直线运动的加速度,A为滑块,花快上的遮光板宽△x=3cm;B、C为光电门(与计时器连接,计时精度为0.1ms),D为牵引砝码.滑块A的遮光板通过光电门B的时间为△t1,速度为v1;通过光电门C的时间为△t2,速度为v2
实现了一种14位40 MS/s CMOS流水线A/D转换器(ADC).在1.8V电源电压下,该ADC功耗仅为100mW.基于无采样/保持放大器前端电路和双转换MDAC技术,实现了低功耗设计,其中,无采样/保持放大器前端电路能降低约50%的功耗,双转换MDAC能降低约10%的功耗.该ADC采用0.18 μm CMOS工艺制作,芯片尺寸为2.5 mm×1.1 mn.在40...
