Course Grading Policy
Course Grading Policy • Quiz 20%
• Project 20%
• Midterm Exam 20%
• Final Exam 40%.
Exams • All the exams are closed book with an one-sided letter-sized notes
allowed for Midterm Exam and a two-sided paper for the Final Exam. All grades become final one week after they are returned in class.
• Midterm: 3/6/13 class time
• Final: 5/10/13 2:00p.m. – 4:45p.m.
Homework and Project • Homework will be assigned on a bi-weekly basis and be collected at the
beginning of the class on the due date except the first homework. No late homework. The homework solution will be posted on the professor’s webpage. Some of the homework and the project require the use of cadence/analog artist design tools; tutorial will be given at the beginning of the semester. In order to use Cadence tools at UTD, a UTD UNIX account is required. It is OK to use Cadence tools at your workplace if preferred.
Any student scored 80/100 in the
final examination will automatically
get A.

Academic Honesty
It is the responsibility of the instructor to
encourage an environment where you can learn
and your accomplishments will be rewarded
fairly.
Any behavior that compromises the University’s
rules of academic honesty will be reported to the
Dean of Students.
The penalty of academic dishonesty ranges from
receiving F grade in this class to being expelled
from the university.

DIGITAL CIRCUITS ARE ON OR OFF
‘ANALOG DEALS WITH THE GRAY’†
“Global use of products such as cell phones, digital cameras, digital music players and satellite radios continues to grow. And more content, such as music, video and data, are being digitized to run on such devices. In order for digital devices to operate, they need chips that can take signals from the real world -- such as sound, power and temperature -- and compress them into a format that can be understood by a computer as zeros and ones.”
“The demand for many types of analog chips in the $32 billion-a-year analog market continues to grow. So does demand for these specialized designers.”
“With digital engineers outnumbering analog ones by an estimated 200-to-1, one headhunter has even said recruiting analog engineers is like using a pig to sniff out truffles in the forest.”
† Dennis Monticelli, Fellow at National in Santa Clara, quoted by MercuryNews http://www.siliconvalley.com/mld/siliconvalley/13493561.htm

Analog Education†
“Analog chip design is highly collaborative -- passed down from generation to generation, like artisans learning from master tradesmen.”
“Analog engineers describe their apprenticeship much like the residency that doctors go through at a hospital. Because there are few automated tools in the field, they learn how to do chip layouts from being mentored and hearing the stories, tricks and mistakes of others.”
“Many companies, such as Texas Instruments, the leader in the field, and others like National Semiconductors, Analog Devices, Maxim and Linear, sponsor programs at universities, and then recruit heavily from that pack of engineers.”

Key Achievements: • Developed dynamically-biased shunt feedback in the LDO to
minimize output transient overshoots and undershoots under massive load step changes.
• A 20mV undershoot under load step changes of 200mA/100ns.
