• Basic MOS Device Physics
❖In this section, we analyze the generation and transport of charge in MOSFETs as a function of the terminal voltages.
• Basic MOS Device Physics
❖In digital circuits, it is customary to use the “switch" symbols depicted in Fig. 2.5(c) for the two types, but we prefer those in Fig. 2.5(a) because the visual distinction between D and S proves helpful in understanding the operation of circuits.
❖注意： as a visual aid作为视觉辅助

• Basic MOS Device Physics
❖Since in most circuits the bulk terminals of NMOS and PMOS devices are tied to ground and Vdd, respectively, we usually omit these connections in drawing Fig. 2.5(a).
❖注意： objective ; derive; elevate; abstraction
Design of Analog COMS Integrated Circuit
• objective
objective--由object（受体）而来，表示“受体的 结果”，即此动作影响下的事物结果，顺理成章的。
