This paper presents a design of single photon avalanche diode(SPAD)light detection and ranging(LiDAR)sensor with 128×128 pixels and 128 column-parallel time-to-analog-merged-analog-to-digital converts(TA-ADCs).Unlike the conventional TAC-based SPAD LiDAR sensor,in which the TAC and ADC are separately implemented,we propose to merge the TAC and ADC by sharing their capacitors,thus avoiding the analog readout noise of TAC’s output buffer,improving the conversion rate,and reducing chip *** reverse start-stop logic is employed to reduce the power of the *** in a 180 nm CMOS process,our prototype sensor exhibits a timing resolution of 25 ps,a DNL of+0.30/−0.77 LSB,an INL of+1.41/−2.20 LSB,and a total power consumption of 190 mW.A flash LiDAR system based on this sensor demonstrates the function of 2D/3D imaging with 128×128 resolution,25 kHz inter-frame rate,and sub-centimeter ranging precision.

针对卷积神经网络参数量大、层数深、泛化性能弱的问题,提出了一种基于多尺度多路径集成网络(Multi⁃scale Multi⁃path Convolutional Neural Network,MCS⁃CNN)的轴承故障诊断方法。首先,提出多尺度卷积块,利用深度卷积和逐点卷积来降低网络参数量、增加网络宽度,有效提取多尺度特征;其次,提出集成块,利用多路径的连接方式将低级和高级特征连接起来以增加网络深度,进而提高模型诊断精度;最后,在凯斯西储大学轴承数据集上进行验证。结果表明,在高噪声和跨负载场景下的故障诊断精度分别可达97.5%和98.25%,在混合场景下相较于现有的诊断方法精度提高了15百分点以上,有效表明了此方法的鲁棒性和泛化性。
