Thermal Design Power (TDP) is a term commonly used in the thermal management of consumer electronics. While the usage of this terminology may vary across the industry, it commonly refers to the amount of power that a device may dissipate indefinitely, in a given thermal environment, without exceeding the temperature limits of the device. The TDP for a consumer electronics … [Read more...]
Calculating Interface Resistance
Introduction The exposed surface area of many of today’s high-powered electronic packages is no longer sufficient for the removal of the heat generated during normal operation. Heat sinks are a commonly-used, low cost means of increasing the effective surface area for dissipating heat by means of convective air cooling. While the use of a heat sink lowers the fluid-side … [Read more...]
Thermal Modeling of a Silicon Germanium (SiGe) Radio Frequency Integrated Circuit (RFIC) for Wireless Communications
The creation, transport and storage of digital information are growing at rates of 40% to 50% annually, with video, mobile broadband, and machine-to-machine communication being the main drivers. The implementation of 5G wireless networks is enabling this growth and heralding a new era of revolutionary applications and functionality due to bandwidth increases and communication … [Read more...]
Statistics Corner: Modifying Sample Size
ABSTRACT Reliability verification often requires that a specific number of components be tested to a predetermined level of testing to demonstrate that none of the samples fail. This article describes a statistical approach for justifying the use of fewer samples by subjecting them to a more severe level of testing. BACKGROUND Reliability verification often includes … [Read more...]
Statistics Corner: Probability
Statistical analysis is needed because data always have some degree of uncertainty; a value that we determine from a single measurement, or even set of measurements, is not necessarily going to tell us exactly what value we will determine with additional measurements. Statistical analysis uses the mathematics of probability to create tools that we can use to deal with … [Read more...]
