Telescopic cascode input stage Folded-cascode input stage Class A output stage Source followers output stage Push-pull output stage Vocabulary differential , magnify, widespread , efficiency Structure Reading/writing techniques Of, relating to, or showing a difference. 差别的：差别的、关于或显出差别的 Constituting or making a difference; distinctive. 区别的：构成或制造差异；显著 Dependent on or making use of a specific difference or distinction. 特异的：取决于或利用专门的特征或特性的 Mathematics Of or relating to differentiation. 【数学】 微分的：微分的、与微分学有关的 Involving differences in speed or direction of motion. 差动的：涉及速度或运动方向不同 Mathematics 【数学】 An infinitesimal increment in a variable. 变量无限小的增量 The product of the derivative of a function containing one variable multiplied by the increment of the independent variable. 微分：用独立变量乘以含有一个度量的函数，然后对其求导所得的结果 Differential gear. 差动齿轮 A difference in wage rate or in price. 工资级差：工资或价格上的差异 The first stage will be the differential amplifier. This stage can magnify the differential signals. 第一级是差分输入级，输入级能够放大差分信号。 The differential amplifier circuit is an extremely popular connection used in IC units. 在集成电路单元中，差分输入级是通常的连接方法。 The traditional differential input stage has an advantage of simple structure, large bandwidth, but it has low gain. 传统差分输入级结构简单，带宽大，但是其增益低， To make greater in size; enlarge. 使…在尺寸上变大；放大 To cause to appear greater or seem more important than is in fact the case; exaggerate: 夸大：使看起来比实际情况更伟大或更重要；夸张： To increase the apparent size of, especially by means of a lens. 扩大外观上的
