Thermal Time Constant Extraction for HBTs from S-Parameter Measurements

AEU - International Journal of Electronics and Communications, 2003
In this letter we present aï¿œnovel approach to extract the thermal time constant of HBTs from S-parameter data. The method is based on aï¿œcalculation of the frequency dependent negative output conductance of the devices due to self-heating effects.

Thermal time constant (TTC) measurements

Defense + Security
Thermal time constant (TTC) measurements are fundamental for characterizing the temporal response of thermal imaging systems. Currently, there are significant variations in the reported values between laboratories due to differing methodologies.

Thermal performance enhancement of phase change material heat sinks for thermal management of electronic devices under constant and intermittent power loads

International Journal of Heat and Mass Transfer, 2021
Metal fin enhanced phase change material (PCM) has been successfully demonstrated as an effective approach for electronic devices cooling, especially in the case of high-power density for only a limited period.

The use of thermal time in plant studies has a sound theoretical basis provided that confounding effects are avoided.

Journal of Experimental Botany, 2018
The use of thermal time is essential in plant studies and crop growth modeling because correcting time for temperature allows working in fluctuating conditions as if temperature was constant. However, thermal time is often seen as a loose concept because
