Principles of Semiconductor Devices

The purpose of this text is to explore the internal behavior of semiconductor devices, so that we can understand the relation between the device geometry and material parameters on one hand and the resulting electrical characteristics on the other hand.

Principles of Semiconductor Devices 

Principles of Semiconductor Devices  

"The Primary Focus: The MOSFET and CMOS Integrated Circuits The Metal-Oxide-Silicon Field-Effect-Transistor (MOSFET) is the main subject of this text, since it is already the prevailing device in microprocessors and memory circuits. In addition, the MOSFET is increasingly used in areas as diverse as mainframe computers and power electronics. The MOSFET’s advantages over other types of devices are its mature fabrication technology, its successful scaling characteristics and the combination of complementary MOSFETs yielding CMOS circuits."

Some of the Topics
  • Schottky diode current
  • Metal-Semiconductor contacts
  • Electrostatic analysis of a p-n diode
  • Reverse bias breakdown
  • Optoelectronic devices
  • Light Emitting Diodes (LEDs)
  • Ideal transistor model
  • MOSFET SPICE MODEL
  • Power MOSFETs

Engineering Electronics Shop Page

Engineering Electronics Shop Page

The Shop Pages are intended to provide students and staff with access to Internet E.E.-related resources, to explain in detail the functioning of our labs and Shop, and to provide information of particular interest to any E.E. student designing electronics projects. Web readers outside of the University of Nebraska - Lincoln campus should know that some of the services mentioned on these pages are applicable to UN-L only.

gedasymbols.org - gEDA suite

gedasymbols.org - gEDA suite

gedasymbols.org. This website is a repository for symbols, footprints and documentation that are useful to anyone using the GPL schematic creation program gschem or the GPL pcb layout program PCB. The misson of gedasymbols.org is to increase the usage of the gEDA suite of tools by distributing symbols and footprints for these programs.

Please note that this site is undergoing transition (as of Feb 2006 at least) so please bear with us while we get our act together. Meanwhile, here are some links to relevent information:

gEDA - full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.

Open Programmer PIC and Atmel

An open source USB programmer for PIC micros, I2C EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices.

Open Programmer PIC and Atmel

  • Completely free and Open Source (including firmware)
  • Programs PIC10-12-16-18, 24xxxx I2C EEPROMs, some ATMEL micros, communicates with generic I2C & SPI devices (see supported devices)
  • USB interface, HID class (same as keyboards, mice, etc.)
  • Self powered
  • Doesn't need drivers
  • Built from easy to find components (estimated cost ~10€)
  • Hardware generated timings for maximum speed and reliability (writes a 18F2550 in 15s, 8s under Linux)
  • Doesn't saturate your CPU and doesn't suffer when other programs are running
  • Open source control programs for Linux and Windows

CompuPhase articles and Application notes

CompuPhase articles and Application notes CompuPhase

On-line publications "for programmers"; they are also written "by programmers".

CompuPhase develops electronic designs, printed circuit boards, prototypes of custom apparatus and the embedded software that runs on the devices. Examples of such apparatus are the various LED-panels that we set up in several exhibit centres, under contract of Podium (Netherlands). Look also at our list of recent projects.

Joar Falstad - Low cost industrial IO

Combine standard Industrial I/O cards and a multimedia PC

The idea is to make the use of low-cost , massproduced industrial I/O cards in conjunction with a multimedia PC easy , yet powerful and flexible.

  • Advanced automatic spot announcing machine
  • Time & masterfile controlled analog conversion
  • Alarm generator for ships , schematic
  • PLC add on / PLC controlled analog multiplexer schematic
Composing examples using lowcost massproduced industrial standard analog / digital I/O cards :

Special ideas, programming  and news

Standard analog  digital I/O cards  Interface to PC

The function of an indirect regulator  like a thermostate, a textfile listing the correct unitvalues and the PC-clock was  the main  components used while composing / writing this program  . A non complex  program idea . This program is easy to learn and  accurate in practical use
