Simulator
As shown on the V-I curve in figure 1, the LED has a forward voltage VF and a operating resistance (Rd). When using a resistor as loading, the V-I curve of the resistor is not able to simulate the V-I curve of the LED as shown in blue on figure 1. This may cause the LED driver to not start up due to the difference in V-I characteristic between the resistors and the LEDs. When using Electronic Loads, the CR and CV mode settings are set for when the LED is under stable operation and therefore, is unable to simulate turn on or PWM brightness control characteristics. This may cause the LED driver to function improperly or trigger it’s protection circuits. These testing requirements can be achieved when using a LEDs as a load; however, issues regarding the LED aging as well as different LED drivers may require different types of LEDs or a number of LEDs. This makes it inconvenient for mass production testing.

Materials Development Corporation
A comprehensive set of analyses for junction diode or Schottky barriers begins with C-V data gathering that adjusts the voltage step to the slope of the C-V characteristics. This assures an optimum set of C-Vdata whether the voltage range is small or large. Doping profile and resistivity profile are both available at the touch of a key. Plots of 1/C2 - V or Log(C) - Log (V+ phi) show doping uniformity and doping slope factor. Exclusive recalculation options allow adjustment of stray capacitance and area to facilitate calibration using a standard reference wafer of known doping or resistivity.

Integrated Video Filter With Selectable Cutoff Frequencies For RGB, HD/SD, Y, C, And CV
ADA4410-6
-
The ADA4410-6 is a comprehensive integrated filtering solution that is carefully designed to give designers the flexibility to easily filter and drive many types of video signals, including high definition video. In the RGB/component channels, the cutoff frequencies of the sixth-order filters can be selected by two logic pins to obtain four filter combinations that are tuned for RGB, high definition, and standard definition video. Cutoff frequencies range from 9 MHz to 36 MHz.
