This article presents a novel alternative for measuring the heat power generated by microelectronic devices during their designing stages. The proposed system is comprised of an uncommon geometry and a signal-processing measuring strategy based on the calorimetric principle and natural convection. The calorimeter is nonconventional compared to others proposed in the literature because it does not require an external power supply or internal moving parts. Therefore, this device features a low-cost operation. In addition, the calorimeter's geometry and design make able to be implemented at any place, as well as enhancement-adaptable. Furthermore, the thermal behavior is studied based on experimental data and numerical simulations to characterize the system properly. Thus, the calorimeter is modeled as a Cauchy problem by an ordinary differential equation to find the transient time constant. Several testing devices ranging from 1 to 20 W were used. Therefore, an algorithm was developed to determine the net heat power in a reduced time. The slowest procedure identified using the proposed algorithm is a 1-W device with less than a half-time constant. Finally, the time reduction when employing devices with power dissipation higher than 20 W is also discussed.

用于微电子器件热分析的新型量热方法


本文提出了一种测量微电子设备在设计阶段产生的热功率的新颖替代方案。所提出的系统由不常见的几何形状和基于量热原理和自然对流的信号处理测量策略组成。与文献中提出的其他热量计相比，该热量计是非常规的，因为它不需要外部电源或内部移动部件。因此，该装置具有低成本运行的特点。此外，热量计的几何形状和设计使其能够在任何地方实施，并且具有增强适应性。此外，基于实验数据和数值模拟研究了热行为，以正确表征系统。因此，通过常微分方程将热量计建模为柯西问题，以找到瞬态时间常数。使用了 1 至 20 W 的多种测试设备。因此，开发了一种算法来在更短的时间内确定净热功率。使用所提出的算法识别出的最慢过程是具有小于半时间常数的 1W 器件。最后，还讨论了采用功耗高于 20 W 的器件时的时间缩短。
