Information regarding the current-voltage amplifier



Project: multi-channel DAC controlled by a PC through either a PCI card or the USB port, with the following requirements:

  • 16 bit (or more) parallel input DAC chip
  • Manual reset to zero (clear)
  • Power on clear
  • Manual oscillator (555 timer output) as a clock for manual testing and with a tunable frequency
  • Manual up and down and stop switch
  • All mechanical switches should be glitch free
  • Each channel requires:

1.      One wire for pulses

2.      One wire for load

3.      One wire for clear

4.      One wire for write

5.      A binary counter up to 16 bits

6.      BCD display or similar feature, showing the counter’s output

7.      The output of the counter is then fed to the parallel-in DAC

  • Need at least 8 channels, with a possibility for future expansion
  • All external components be put in a box
  • The power comes from either (car) battery or 120V ac outlet, selectable from a switch
  • Use LEDs as power or logic indicators when needed


Microelectronics Design Laboratory; (2 credits)

Prerequisite: ENEE306 and ENEE312 and completion of all lower-division technical courses in the curriculum. For ENEE majors only. Senior capstone project laboratory, where student design and build fairly sophisticated circuits, mainly composed of discrete transistors and integrated circuits. Many of the projects are designed to require that students synthesize from what they have learned in many of the disciplines in electrical engineering. Students learn they can actually use their knowledge to build something very practical, which may include a high-fidelity amplifier, a radio, a memory cell, a transmitter, etc.
