21. Modeling the Inter-Electrode Capacitances of Si CoolMOSTM Transistors for Circuit Simulation in High Efficiency Power Systems
Published: 9/12/2010
Authors: Nanying Yang, Jose Miguel Ortiz, Tam Hoang Duong, Allen R Hefner Jr., Kathleen Meehan
Abstract: The CoolMOSTM transistor is a novel power MOSFET type device that utilizes a super-junction embedded within its drift region in order to improve the trade-off between on-resistance and breakdown voltage. The super-junction results in unique inter-e ...
