This invention relates to a window A/D converter used in digital supply controllers composed of a PMOS difference input pair, a CTAT offset current generation circuit, two loop oscillators and a digital part including two n-bit counters, one n-bit comparator, one n-bit subtracter and an n-bit D trigger, in which.

本发明属集成电路技术领域，具体为一种适用于数字电源控制器的窗口式模数转换器。它由一个PMOS差分输入对、一个CTAT偏置电流产生电路、两个环路振荡器和数字部分组成。数字部分由两个n位计数器、一个n位比较器、一个n位减法器、一个n位D触发器组成。

Root hairs of wild type were intensely induced in the presence of NAA, while the gls mutant was insensitive to NAA induced root hair initiation; Lateral roots of the wild type were dramatically decreased when treated with 2,4-D, while the gls mutant was insensitive to 2,4-D induced reduction in lateral root initiation; The seminal root length of wild type showed no obvious changes by the treatment with IAA, but the gls mutant was supersensitive to IAA with dramatic reduction in seminal root length, suggesting that the interactions of GLS gene with different hormones may involve different mechanisms.

外源NAA 处理强烈诱导野生型根毛发生，而gls突变体则不敏感；外源2，4-D处理，野生型侧根急剧减少，gls突变体则不敏感；外源IAA处理，野生型种子根长变化不明显，而gls突变体超敏，种子根长迅速变短，表明GLS基因与不同激素有不同的互作机制。
