Additionally, an ideal filter must have an impulse response that extends to infinite time before and after the pulse peak and, if the filter is to be causal (output response occurs after the input is applied), the peak output would occur an infinite time after the input. This would

MOS Capacitor - Chenming Hu

advanced transistors (see Section 7.4). The MOS capacitor is not a widely used device in itself. However, it is part of the MOS transistor—the topic of the next tw o chapters. The MOS transistor is by far the most widely used semiconductor device. An MOS transistor (Fig. 5–2) is an MOS capacitor with two PN junctions flanking the capacitor.

MOS Transistor CHAPTER OBJECTIVES This chapter provides a comprehensive introduction to the modern MOSFETs in their on state. (The off state theory is the subject of the next chapter.) It covers the topics of surface mobility, body effect, a simple IV theory, and a more complete theory applicable to both long- and short-channel MOSFETs.
