Optimal Design of Circuits for Optoelectronic Devices

Dr. Vuza collaborated between 1998 – 2002 with Senior Engineer Dr. Marian Vladescu from Electromagnetica Goldstar on a series of researches concerning the optimal design of circuits for optoelectronic devices, focusing on optoelectronic sensors. The results obtained were concerned with the comparative evaluation of performances of optoelectronic sensors based on different types of synchronous demodulation, by employing both theoretical methods (Fourier analysis) as well as numerical experiments (SPICE simulations). The results made the subject of the communications listed below.
