ECE137B : 2008
DO NOT GO TO THE SCHEDULED LAB HOURS during the first week of classes. The laboratory/design content of the class is run on an independent basis. Design projects are assigned and a due date is given. Students work in the lab constructing and testing their designs, working in the lab at whatever time they find most suitable to work

More hints regarding the fiber optic project: hints_lab2.pdf
The lab assigments a *major* single project, extended over
the full quarter.
You have a choice: do one of the two projects below
First choice of lab project: ece137b_lab_project_2008_1.pdf
Second choice of lab project: ece137b_lab_project_2008_2.pdf
Third choice of lab project: ece137b_lab_project_2008_3.pdf
Matlab simlulation files for the digital power
amplifiers:
shorter_pwm_plus_feedback.m fast running less accurate pulse width simulation
longer_pwm_plus_feedback.m slow running more accurate pulse width simulation
power_ds.m this is the delta-sigma simulation file.
raised_cos_baseband_filter2.m this is is a sub-file needed for all
simulations
hann.m this
is is a sub-file needed for all simulations
summary_PWM.pdf this is a set of images from the PWM simulations.
We do not need a preminary report
for check off #1
First check off date: Thursday
April 24 and Friday April 25.
Second preliminary report: May 2,
5 PM in HW box
Second check off date: Thursday
May 8 and Friday May 9.
Third preliminary report: Friday
May 30, 5 PM in HW box
Third check off date: Thursday
June 5 and dFriday June 6
Reports due Monday June 9, 8 AM in
HW box
Lab is CLOSED on checkoff days except 60 minutes prior to your check
off time.
So,
you should plan on having your project fully complete before these dates..
The main text for the class is the online lecture notes-
these are available via the links below. You will also need to have a quality
analog IC design text. If you don't have one, recommended texts would include Grey and Meyer: Analysis
and Design of Analog Integrated Circuits, Any edition
or Microelectronic Circuit Design, 2nd
edition or 3rd
edition, R.C. Jaeger and T.N. Blalock, or Fundamentals
of Microelectronics, Behzad Razavi
These can be purchased online from many vendors. Older editions have the advantage that used copies can be obtained at a lower price. Any of these books would be just fine.
It is advisable to read and study indicated sections of the text in detail.

Final exam solutions:
the data sheets give a spice Model with
tau_f and Ccb and Cje specified.
use the formulas
Ccb(Vcb)=Cjc / (1+Vcb/Vjc)^MJC
Cje(Vbe)=Cje/(1+Vbe/Vje)^MJE
The datasheets for the power
transistors are missing the ft and Ccb specifications. These are:
ft = 3.0 MHz (IC = 250mA, VCE = 10
V) for both NPN and PNP
Cob = 100 pF (IE = 0, VCB = 10 V) for both NPN and PNP
While these are high-current devices, they can also be used as small-signal devices with bias currents in the range of 1-100 mA. At these lower currents, the data sheet does not provide adquate Gm & Gds data, and a curve-tracer must again be used.
