ESE562: Analog Integrated Circuits – Final Project
In this assignment you need to design an analog processor that computes the third root of a number using a polynomial function F(x) as :
F(x) = x2
1. Using MATLAB plot F(x) vs x for - 10 < x < 10. [5 points]
2. Design a circuit that takes the x as inputs (currents or voltages) and produces an output F(x). Simulate the circuit using CADENCE tools. Export the data points from the simulation into a text file and import the data into MATLAB for analysis. [10 points]
3. Modify the previous circuit to solve: x2 = 2 such that x = √2.You would need to perform a transient simulation starting with some initial condition x0 after which the circuit stabilizes to a final steady-state. Be mindful of feedback and stability issues. [15 points]
4. For your presentation/report you need to submit 4 slides. (a) Summary slide – Algorithmic level innovation and approach. (b) Circuit schematic
(c) Results: Plot comparing MATLAB simulation and circuit simulation for question 2.
(d) Results: Plot showing transient simulation of the circuit estimating the value of √2 in question 3. Also, compare the accuracy with the correct solution.
SUPER BONUS
You will get an A in this course if you are able to implement a circuit that can estimate the value of π using the concepts in 2-4.
