EE40 Summer 2011 Neel Shah Reading Assignment 15 8/1/2011 Boilerplate: Reading assignments are short exercises that verify your understanding of the required reading. All chapters and page numbers are in reference to “Foundations of Analog and Digital Electronic Circuits” by Anant Agarwal and Jeffrey Lang. This assignment is optional; however it may count towards a final grade boost should you require it. 1. The MOSFET model includes a dependent source. What kind of dependent source is it? a. Voltage controlled voltage source b. Current controlled voltage source c. Voltage controlled current source d. Current controlled current source 2. The dependent source has a multiplier of

Unformatted text preview: g G , which is dependent on the FET construction. What are the units of g G ? a. Dimensionless (no units) b. Ohms (Volts/Amps) c. Siemens (Amps/Volts) 3. What region of MOSFET operation (cutoff, triode, saturation) do we want to operate in? 4. For an nMOS, should the drain be connected to power or ground? What about the source? 5. Suppose we have an nMOS transistor with the following properties: ± ² = 1.6 × 10 ³´ µ ¶ ,· = 20 ¸¶,¹ = 1 ¸¶,º » = 0.5 º What is the drain current when the applied gate voltage is º ¼ = 2 º , and the voltage at the source terminal is º ½ = 0.5 º ?...
