Bandwidth and offset of CMOS folding preprocessing circuit are the main factors, which limit the dynamic and static characteristics of folding-interpolating ADC.
CMOS折叠预处理电路的带宽和失调是限制折叠内插式adc的动态和静态特性的主要原因之一。

This lack of static, DC offset current in the output transformer means that the core can be made smaller, because it requires no air gap to prevent core saturation from the static DC offset current.
