Name (Last, First) EECS145M 1999 Midterm #2 Page 1 Derenzo UNIVERSITY OF CALIFORNIA College of Engineering Electrical Engineering and Computer Sciences Department EECS 145M: Microcomputer Interfacing Laboratory Spring Midterm #2 Monday, April 19, 1999 Closed book (equation sheet handed out with this midterm) Calculators OK You must show your work to get full credit PROBLEM 1 (50 points) Design a computer-controlled system for the automatic testing of 12-bit A/D converters. Y ou are provided with the following: A microcomputer equipped with one 16-bit parallel input port and two 16-bit parallel output ports A 16-bit D/A converter with ±1 LSB absolute accuracy error, ±0.5 LSB linearity error, and ±0.5 LSB differential linearity error. You may assume the following: The A/D converters are plugged in manually and tested by your computer system one at a time The A/D converter requires a “start conversion” low-to-high signal and after conversion provides a “data ready” low-to-high signal that goes low when “start conversion” goes low. The A/D reference voltages are V
