Units for Offset Error and Gain Error The unit , which is used in this example, is defined as: Thus, an error in (volts) translates into as follows: where is the full scale range of the ADC and is the number of
applying an input voltage of 0 always results in an output value of 0. However, gain errors cause the actual transfer function slope to deviate from the ideal slope. This gain error can be measured and compensated for by scaling the output values. An example of a 3-bit ADC transfer functi...
Full Scale 指0 dBFS 的位置, 0 dBFS就是最大编码电平,不同ADC的0 dBFS 实际对应值不同,它也是数字峰值表满度的参考电平。数字信号以ADC能处理的最大模拟信号的编码为最大值,即0 dBFS, 实际数字信号的幅度的编码相对于这个最大值的信号编码所代表的幅度之比,即为满度相对电平(dBFS)。因为规定最大值为0 ...

Gain errors are corrected in an ADC chip including an integrator (17), a comparator (30), and a digital filter (37) by storing a gain-adjusted LSB size based on measured gain error in a memory (44). The gain-adjusted LSB size is applied to the digital filter to cause gain-adjusted ...

关系到对直流量测量的精确度的问题，所以很关心offset error和gain error对结果的影响以及这两个参数的...
这是我们测试方案的简单图示:在IN+和IN-两端加电压(±163.84mV以内),使用六位半万用表测IN+和IN-两侧的电压,读04h(Vshunt)寄存器的值。如此得到几组数据,使用函数拟合得到一个一次函数,斜率减一即为Vshunt Gain error。目前,我们更换过IN+和IN-两侧的电源,使用过ADC或者电源或者电源分压,结果都不理想。在IN...

The single-ramp single-slope (SRSS) analog-to-digital converter (ADC) is a promising candidate for column-parallel architectures. This paper, for the first time, quantitatively analyzes the ramp gain error in the ramp-input stage (RIS) that is the crucial component in such ADC, and verifies...
