LSB是指最低位一个bit的权值,比喻ADC是一把尺子,那LSB则是它的最小刻度。LSB=Vfs/(2^N),Vfs为full scale voltage,N为ADC的分辨率(Resolution)。 2、Offset Error Offset Error通常又被叫做Zero-Scale Error。简单理解,对于ADC,输入的Analog信号,只有抵消(或叠加)Offset Error,才能正常进行AD转换;而对于DAC,输...
实验结果表明,相比基准设计,在典型的ViT工作负载下,所提出的架构可降低44.1%~55.9%的能量-延迟积(Energy-Delay-Product,EDP)。该工作以《An In-Memory Computing Accelerator with Reconfigurable Dataflow for Multi-Scale Vision Transformer ...
要让DAC8811上电时处于满量程状态而不是zero scale,您需要按照以下步骤操作: 1. 了解DAC8811的引脚配置:首先,您需要了解DAC8811的引脚配置,以便正确连接电源和控制引脚。DAC8811有8个数据输入引脚(D0-D7),2个控制引脚(CS和WR),以及一个模拟输出引脚(Vout)。 2. 配置电源:将DAC8811的Vcc引脚连接到所需的电源...

一般来讲,ADC的offset和gain error会比较容易校准。只要外接0V和full scale进行采样,然后得到校准系数。另外,如果需要作温度补偿的话,一般需要加一个温度传感器,然后利用查表的方式来补偿。 4.对ADC和DAC周围的布线有哪些建议? ADC和DAC属于模拟数字混合型器件,在布局布线时最重要的是要注意地分割,即模拟地和数字地...
