Active Resistor. • Gate and Drain of MOS transistor are tied together. • I-V characteristics are qualitatively similar to a pn-junction diode (MOS diode). • The MOS diode is used as component of a current mirror and for level translation (voltage drop).
he acronym MOS stands for metal–oxide–semiconductor. An MOS capacitor. (Fig. 5–1) is made of a semiconductor body or substrate, an insulator film, such as SiO2, and a metal electrode called a gate. .. thermal generation at a very slow rate (for the same reason the diode reverse leakage current is small.)

IDEAL MIS DIODE. Sl—SlO; MOS DIODE. CHARGE-COUPLED DEVICE. 7.1 INTRODUCTION. The metal-insulator-semiconductor (MIS) diode is the most useful device in the study of semiconductor surfaces. Since the reliability and stability of all semiconductor devices are intimately related to their surface conditions, an
The metal-oxide-semiconductor diode or MOS capacitor is an important structure, which is incorporated in the surface of most semiconductor devices. It forms an essential part of a MOSFET which in turn is an important device used in large- scale integration. Therefore, all the studies related to any kind of MOS device.
19 Dec 2003 Ideal MOS. 0 A. at zero applied bias, the energy difference between the metal work function qФ m and the semiconductor work function qФ s is zero (in other words, the energy band is flat called flat band condition ). 0 B. the only charges that exit in the diode under any biasing condition are those in the

body-drift diode breaks down and significant current starts to flow between the source and drain by the avalanche multiplication process, while the gate and source are shorted together. Current-voltage characteristics of a power MOSFET are shown in Figure 6. BVDSS is normally measured at 250µA drain current. For drain.
They are the basis for MOS memory structures such as Flash memory and. CMOS logic structures. Before we can understand the MOSFET we need to look closely at the MOS diode itself 140.
