Dr. Khondker’s research interests are in the areas of solid state materials and device theory, very large scale integrated circuit (VLSI) design. His research activities involve digital signal processing, modeling and characterization of III-V compound semiconductor devices, Modulation Doped Field Effect Transistors (MODFETs), double-heterojunction structures, multibarrier and resonant tunneling devices.
I. Course Description
An advanced project-oriented course on the design of Very Large Scale Integrated Circuits. Students working in teams will design a CMOS integrated circuit and write a final report. The course will require the use of SPICE, HDL languages (Verilog or VHDL) and several VLSI layout tools. Substantial independent work on advanced topics will be required (for students enrolled in EE547)

Homework 1: (due date: Jan 22)
Exercises 1.3, 1.4, 1.7a, 1.11, 1.12, 1.14 & 1.16 (EE 447 and EE 547)
1.17, 1.18 (EE 547 only)
Homework 2: (Due date: January 31) (You can work in a group of two people) 1. Design and layout a 3:2 priority encoder (see Exercise 1.7b of your textbook) using the JAVA-Electric CAD software. For the inverter, the widths of the NMOS transistor should be 6l and the widths of the PMOS transistor should be 12l. For other gates, use widths for the FETs such that the pull-up and the pull-down paths have strengths comparable to that of the inverter. In the spice deck add 0.1pF of capacitive loads t each output. Simulate using SmartSpice and show the functionality of the encoder. Using the “.measure” statement, estimate the 50%-50% delay between the inputs and output and the 10%-90% Rise and 90%-10% all delays of the output waveforms. What happens if the load capacitance is increased to 0.1pf and 1.0pf? 2. Layout a positive-edge triggered D flip-flop (DFF) (see Fig 1.31 and Fig 1.73 of your textbook) using the JAVA-Electric CAD software. The widths of the NMOS transistor should be 6l and the widths of the PMOS transistor should be 12l. In the spice deck use a 0.1pF of capacitive load at the output, Q. Simulate using Spice show the functionality of DFF. Use a clock with rise and fall times equaling 0.1ns each and a period of 1ns. Design a testbench for the data input and clock. Report a few relevant delay measurements from your simulations. What happens if the load capacitance is increased to 1pf and 10pf? Hints: This zip file contains examples of a library, the spice header that contains the BSIM3 Model and footer files for spice simulations. Downloads: Homework 3: (due date: Feb 8) Exercises 2.2, 2.4, 2.5, 2.6, 2.14, 2.15, 2.22 2.21, 2.3 (extra problem for EE 547 only) Homework 4: (group project 1) (due date: Feb 22) Download the following library. There are a few layouts missing in the library. You need to complete the physical layouts and perform spice analysis for every layout of different sizes (1X, 2X etc) in the same group that you have designed. In other words, if you have designed AND4_4X, your analysis should be complete for all AND4 gates from sizes 1X to 4X. For loads we will use inverters of size (1X to 8X with increments of 1X). More details will be discussed in the class. Please see me if you have questions. Homework 5: (due date: Feb 29) Exercises 4.2, 4.3, 4.10, 4.11, 4.15, 4.24, 4.25 4.12 (EE 547 only) Homework 6: (due date: March 7) Exercises 4.30, 4.31 4.33, 4.34 4.35, 4.36 (for EE 547 only) The Final Group Project.
