Pulse and Synchro-Photon Electronics
This book presents the theory of large-signal nonlinear impulse processes occurring in bipolar and field-effect transistors with a Schottky gate, collapse TRAPATT and tunnel diodes, superlattices, and double heterojunction lasers. It evaluates the maximum speed of impulse operation of these elements and experimentally constructs the generation of pulse oscillations with a repetition frequency of up to 1, 2 and 4 GHz. Original or adapted methods of mathematical modeling of processes provide an opportunity to obtain quantitative dependencies of generated pulse parameters, while the book also details the synchro-photon effect. In addition, as shown here, when a semiconductor element is switched on by an electric pulse, and at the same time a pulse of photons synchronously illuminates it, an effect occurs which increases the switching speed of the element by an order of magnitude. At the same time, the switching transient characteristic is shortened by 10 times or more. After applying this effect in pulse generators in the gigahertz frequency range, an increase in the repetition frequency of the generated oscillations is possible.
Ferdinandas Vaitiekūnas graduated from Kaunas Polytechnic Institute, Lithuania, before working at the Vilnius Radio Measuring Instruments Scientific Institute, Lithuania. In 1971, he defended his doctoral dissertation on the topic of microwave, going on to work at the Faculty of Physics in Vilnius University, Lithuania, where he also served as Dean of the Faculty of Professional Development. He is the author of 200 scientific publications, including 20 patents.
