This paper analyze the Electrical, Optical and Thermal (EOT) characteristics of Organic Light Emitting Diode (OLED) using integrating sphere. From the data obtained, critical optical characteristics to be measured for OLED panel panels and suitable measurement methods and conditions for testing OLED panels are discussed. The 2π geometry of the integrating sphere has been employed for testing the OLED...
This paper describes the development of a power device characterization curve tracer based on transient thermal measurement. Experimental test set ups along with the required conditions to mitigate the measurement errors are discussed. The measurement algorithms are implemented in LabVIEW environment as a set up controller. The junction temperature is maintained at the specified set point for carrying...
The fuzzy control technology is applied in the field of temperature and humidity control, which can realize the intelligent control of temperature and humidity. A temperature and humidity fuzzy controller is designed based on CAN bus. So that temperature and humidity can be real-time monitoring and controlled. The principles method and the hardware circuit of this fuzzy control are described. Simulation...
A temperature control system was designed. System structure was established by taking C8051F002 SCM as the core. The interface circuit between SCM and measurement and control computer is designed using MAX3232. Temperature-measure circuit is designed using ADI corporation's chip AD7416. Temperature-control circuit is designed with SCM's two 12-bit DACs. The flow chat of main program is introduced...
Utilization of digital control in the design of power controllers provides designers with the capability to monitor multiple operational parameters of a power converter. This functionality is often harder to achieve with converter designs based on analog controllers. The reason for this difference is that the information used for internal control purposes in the case of a digital controller is digitized,...
In this paper we present the results of surface temperature control of silicon nanowires by using fluorescent thermometry at the nanometer scale. Rhodamine B is one of the stable fluorescent molecules, which rely on the characteristic of temperature-dependent change in fluorescent intensity, and it was used for nano-scale surface temperature sensing interface. The resistive heating on Si nanowires...
Since the very beginning of the flash memory era, the market has been dominated by the floating gate technology. However, as floating gate flash continues along a very steep scaling path, more and more barriers start to appear, limiting further scaling possibilities of the technology. At the same time, other concepts are preparing to take over. This paper concentrates on the prospect of high-k materials...
A high bandwidth critical path monitor (1 sample/ cycle at 4-5 GHz) capable of providing real-time timing margin information to a variable voltage/frequency scaling control loop is described. The critical path monitor tracks the critical path delay to within 1 FO2 inverter delay with a standard deviation less than 3 FO2 delays over process, voltage, temperature, and workload. The CPM is sensitive...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
