Unformatted text preview: t | = 0.5V. Assume that the MOSFET parameter V A = 1/ Î» = 40V, operating at the drain voltage V D = 2V. What region is the transistor operating in? What is the voltage gain v o /v i ? (20%) 2 4. For the NMOS amplifier below, replace the transistor with its T equivalent circuit, assuming that V DD = V SS = 5V, Î» = 0, R D = 10 K â„¦ , Rs = 20 K â„¦ , and g m = 1 mA/V . What are the voltage gains of v s / v i and v d / v i , respectively? (20%) 5. Consider the following circuit, V t = 0.5V, Î¼ n C ox = 80 Î¼A/VÂ² , Î» = 0 with channel length of 1 Î¼m. Find the required values of channel width for each of Q 1 , Q 2 , and Q 3 to obtain the voltage and current values indicated. (20%)...
