Electro-thermal analysis of flexible micro-heater
2015 38th International Spring Seminar on Electronics Technology (ISSE), 2015Micro heaters have particular applications in the gas sensor and the biotechnological field. The micro heaters are used to obtain the desired constant temperatures over the entire heating surface. Additionally the power consumption should be as low as possible.

Analysis of electro-thermal instability in bipolar transistors
2015 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC), 2015This paper illustrates an analytical method to determine the electro-thermal instability due to self-heating and impact ionization in terms of dissipated power and junction temperature. The analysis is carried out for single transistors (corresponding to silicon and gallium arsenide technologies) as well as for scaled devices to appreciate the use of ...

Size-Dependent Electro-Thermal Buckling Analysis of Flexoelectric Microbeams
International Journal of Structural Stability and Dynamics, 2023This paper studies electro-thermal buckling in a flexoelectric microbeam. This first-of-a-kind study focuses on two case-specific types of buckling in microbeams, which are essential to microstructures. Because of the electric fields and high temperatures in their environments, microbeams are susceptible to electro-thermal buckling more often than ...

Electro-Thermal Analysis of Suspended Multiwalled Carbon Nanotubes
2020 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO), 2020This paper studies the electro-thermal property of suspended multiwalled carbon nanotubes (MWCNTs) with high-bias voltages. A compact model of resistance with temperature-dependent parameters is employed for electric modeling of MWCNTs. In the thermal analysis, a compact model of thermal conductivity is considered and the finite difference method is ...

A review of the use of electro-thermal simulations for the analysis of heterostructure FETs
Microelectronics Reliability, 2007Abstract This paper deals with using device-level numerical simulations for the investigation of the electro-thermal behavior of a GaAs-based heterostructure FET. We show a way of dealing with the software/hardware limitations related with the huge disproportion between the electrically active region and the volume relevant to heat outflow.

Experimental analysis of electro-thermal instability in SiC Power MOSFETs
Microelectronics Reliability, 2013Abstract In this paper we experimentally demonstrate that SiC high voltage Power MOSFTEs exhibit an unstable electro-thermal behavior for given electrical conditions, depending on the chip thermal impedance. This instability can lead to hot-spot formation and eventually thermal runaway whit subsequent device destruction after a stressful short ...

Comprehensive electro-thermal(ET) analysis with considering ET coupling
2011 9th IEEE International Conference on ASIC, 2011Temperature and supply voltage directly influence IC performance and reliability. Thus electro-thermal(ET) analysis including power/ground(P/G) analysis and thermal analysis is very important in IC design. But present ET analysis is simply implemented because P/G analysis doesn't consider temperature changes and thermal analysis always assume supply ...

Electro-thermal analysis of Electric Double-Layer-Capacitors
2008 14th International Workshop on Thermal Inveatigation of ICs and Systems, 2008Electric double layer capacitors (EDLCs) operate between rechargeable batteries and electrolytic capacitors with respect to energy and power performance. Prediction of internal heating due to discharge and charge current cycles is one of key elements for producing reliable and safe devices with long cycle-life.

AC analysis and simulation of smart electro-thermal microactuators
2012 IEEE International Conference on Industrial Technology, 2012This work presents the AC analysis of smart microactuator system. The electro-thermal microactuator is modelled in VHDL-AMS and integrated with its driving circuit using Cadence AMS tools. A new design approach is used to generate a variable low frequency oscillator signal. The high voltage driving AC signal is generated by a DC/DC converter biasing an
