Board Design and Spice Modeling
Here we present several typical examples of projects that the lab developed together with the School's researchers. Some of these projects were published in scientific journals.
DBD – Control system for a pulsed gas valve combined with a high voltage discharge
A controller producing short high-voltage pulses of 5000 Volts for a Dielectric Barrier Discharge system. The controller is based on a full FET bridge which operates at MegaHertz frequency. Synchronously to this voltage pulse, the system produces a high current pulse of tens of Ampers to operate a pulse valve operating at a rate of 2000 Hertz. The system is computer controlled through USB communication.
Programmable multi-channel system for characterization of silicon nanowires
An integrated electronic system to operate a silicon nanowire based explosives detector. It consists of 32 channels of source meter with programmable gain. The system is based on a TMS320F28335 controller manufactured by Texas Instruments and controlled by a Windows based software through a USB port.
Rape-drug detection system
A miniaturized electronic system for a "rape-drug" detector, based on a Texas Instruments 430MSP controller.
A miniaturized scanning tunneling microscope (STM) system
A low-cost educational STM system. A mechanical head and an electronic controller connecting via USB to a computer and operated by a CVI based software. The system is based on FPGAs programmed to use a VHDL code.
An ultra-fast amplifier with a low noise for measuring electrical discharges
A fast, high-bandwidth (350 MHz) amplifier for a multi-channel plate detector. The amplifier is designed to measure very fast electrical discharges within a plasma or molecular ensembles. This development was published in the MST journal and was purchased by many research labs all over the world.

A controller for a fast pulsed valve
A pulse generator for a pulsed valve operating at a high rate. The generator supplies pulses with variable widths, with 100 ns resolution, a frequency up to 1000 Hz and an intensity of 300V/100A. The generator is digitally controlled by a logic system programmed with a VHDL code. The system was sold to many laboratories in Europe, the US and Japan.
