Defects can show up in the clock trees that drive scan chains, and even inside blocks of scan cells, which may number in the millions. Jayant D’Souza, technical product director for yield learning ...

Since setting up the collaboration four years ago, VLC Photonics’ deep expertise in PIC test and assembly has been ...

Left panel, superconducting rectifier circuit used to convert AC currents into DC using four superconducting diodes (blue) connected by superconducting interconnects and one smoothing capacitor (C ...

Figure 3 shows a half-bridge test circuit used to perform reverse recovery characterization. Like the pulse pattern described in Figure 1, the high-side device will initially switch on and off to ...

A constant current source with an LM317 voltage regulator is used as the main measuring circuit. The circuit in the following figure ensures that the current at OUT and through the diode will be ...

This current source is composed of transistor T2 (BD140) in 'common base' mode, Zener diode ZD1 (BZX55C 4.7V) and resistor R8 (2.2 kΩ) polarizing its base. A rotary switch allows you to select a ...

A similar result is obtained by using two Zener diodes in series but in opposite directions. In fact, in correspondence with the positive wavefront, one of the two diodes is in reverse bias and as ...

In this article, we will learn how to test SMPS circuit and talk about some of the most basic tests for SMPS and the safety norms that need to be followed to test an SMPS circuit easily and ...
