New Chaotic Oscillator Derived from Class C Single Transistor‐Based Amplifier

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper describes a new autonomous deterministic chaotic dynamical system having a single unstable saddle‐spiral fixed point. A mathematical model originates in the fundamental structure of the class C amplifier. Evolution of robust strange attractors is conditioned by a bilateral nature of bipolar transistor with local polynomial or piecewise ...

Modeling and Simulation of Power MOSFET Using Orcad-Pspice

open access: yesInternational Journal of u- and e- Service, Science and Technology, 2016
This paper provides a macromodel in Pspice (Personal Simulation Program with Integrated Circuit Emphasis) for a trench power MOSFET rated at 70V over a temperature range of -55°C to 175°C. The Pspice macromodel was built using device parameters extracted through experiment. The static behavior of the trench power MOSFET is simulated and compared to the
