ECE137B : 2009

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

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..

Weekly Reading

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:

Transistor Datasheets

small-signal bipolar transistors:

2n3904.pdf    2n3906.pdf

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

medium-power bipolar transistors

mje371rev3.pdf  mje521rev2.pdf

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

 

small-signal MOSFET matched pairs

ALD1106.pdf  ALD1107.pdf ALD1115.pdf  ALD1116.pdf

These are good for general analog design at moderate frequenices.

medium-power MOSFETs

VN0104.pdf  VP0104.pdf

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. 

High-power MOSFETs

IRFU014_N-ch.pdf  IRFU9014_P-ch.pdf

These would serve well as a complementary power output stage at audio frequencies.

High Speed Analog Comparators

AD790.pdf   Analog Devices: Precision, expensive.

LM160.pdf   National Semiconductor (LM360/LM160): Cheaper, Probably good enough.

CMOS D-type flip flops

cd4013.pdf  This part is sufficiently fast for the power delta-sigma adc

MM74HC74A.pdf This is a faster device for use in the fiber optic project 

CMOS XOR gate

MM74HC86.pdf  This is a faster device for use in the fiber optic project

Fiber Optic Components

LED: IFE98.pdf

PIN Photodiode:  IFD91.pdf

 

Medium-Speed Op-Amps

LF351.pdf  LF353.pdf

These are Bi-FET op amps with ~4MHz unity-gain bandwidth and ~13 V/us slew rate.
