Device Knowledge
1. p+/n- junction and p-/n+ junction, which has a higher breakdown voltage? Why? For a p+/n- junction having NA and ND, what is the approximate function of junction capacitance (Cj) vs. reverse biased voltage (VR)?
2. Draw the cross-section of a CMOS inverter. Draw the parasitic structure on the cross-section. Describe ways to prevent “latch-up”?
Circuit Analysis
3. See the figure below.
a. Draw the bode plot for this
