ECE165 - Midterm ECE 165, Prof. Buckwalter 1 SHOW ALL WORK. NO CREDIT UNLESS JUSTIFIED. Total 150 Points Problem 1 Dynamic Behavior- 30 Points The capacitance of our new device is quite simple. You can assume there is only gate capacitance, gate-drain capacitance, gate-source capacitance. The material between the gate, channel, drain , and source has a capacitance per unit area of . The device geometry is shown below: Determine the Dynamic Inverter Performance Metrics a)Calculate the capacitances for the following device capacitances: (5) C g = ; C gd = ; C gs = . b)What is the internal and external capacitance with a minimum size inverter load? (5) C int = ; C ext = . c)Calculate the H-L and L-H propagation time. t PHL = ; t PLH = . (10) (I expect to see a numbers!) C dielectric e pF nm 2 --------- =
