Circuits with transistors Tutor for College and Faculties, Math and Physics for High School

Hello everybody! I am current Professor of Electronic Devices (Transistors, Diodes and Semiconductor Physics) at Polytechnic University from Bucharest, Romania, since 1999 till now. I can teach and assist you in solving problems or theory comprehension with pn-junctions, MOS capacitors, and usual transistors - Bipolar, JFET and MOS, including Atlas simulations for Transistors, or Spice simulations for basic circuits. Also, I have experience in Mathematics for High School (Geometry, Trigon, Algebra, Math analysis with derivative and integrals). In Physics I can teach you about Electricity, Mechanics and Thermodynamics at High school level. Also I can teach a brief series of courses about "Secrets of Learning" in Electronics or Math or Physics. If you are curios to speak and learn with a Professor from another Continent or Country, please try me. About my English, my publishing papers in Electronics, applied Math, e-Learning Conferences - you can find at: Google Academic - Cristian Ravariu ResearchGate page: search - Cristian Ravariu
