2) Define enhancement mode and depletion mode MOSFET.
3)Describe what does it meant by threshold voltage, width-to-length (W/L) ratio, and drain-to-source saturation voltage.
4)How do you prove that a MOSFET is biased in the saturation region?

2) In the DC analysis of some MOSFET circuits, quadratic equations in gate-to-source voltage (Vgs) are developed. How do you determine which is of the two possible solutions is the correct one?
3) Explain how pinch off voltage occurs?]]> 2017-12-13 06:18:22 UTC https://padlet.com/noorjannah/2tczhx7anoll/wish/215677392 SUMMARY noorjannah https://padlet.com/noorjannah/2tczhx7anoll/wish/215677829 1) Understand the physical structure and DC electrical characteristics of the MOSFET.
2) The current in MOSFET is controlled by the gate voltage. 
3) In the nonsaturation bias region of operation, the drain current is also a function of drain voltage, whereas in the saturation region of operation the drain current is essentially independent of the drain voltage. The drain current is directly proportional to the W/L ratio of the transistor. Therefore W/L is the primary design variable in MOSFET circuit design.
4) Basic applications of MOSFET include switching currents and voltages, performing digital logic functions and amplifying time-varying signals.
5) MOSFET circuits can provide constant-current biasing.]]> 2017-12-13 06:22:59 UTC https://padlet.com/noorjannah/2tczhx7anoll/wish/215677829 1) Two-Terminal MOS Structure noorjannah https://padlet.com/noorjannah/2tczhx7anoll/wish/215679823 The heart of MOSFET is the metal-oxide-semiconductor capacitor .
