Thermistors are temperature sensing instruments that have a semiconductor material in them. The property of this material is to exhibit a large and precise change in its electrical resistance when subjected to small change in its body temperature.(more)

Surface Mounted Device resistors, also known as SMD resistors are used by millions of electronic equipment manufacturers. These manufacturing firms range from cell phones and MP3 Players and televisions to computer accessories like CPU,(more)

It is apparent that designing a laser driver will save money in the long run for high volume production laser systems. But the cost for this route is not low: high design cost, long design time, high risk to fail or result in sacrificed performance because designing a good laser driver requires years’ experience and many times failure,(more)

Piezoelectric crystal is a non-centrosymmetric crystal, deforming under the mechanical force, which causes the relative displacement of the charged particles, so that positive and negative bound charges are produced on the crystal surface.(more)

What is adaptive PID control system? PID stands for proportional, integral and differential control system. Adaptive PID control system refers to an intelligent PID control system with self-learning capability that adapts to changes in external conditions.(more)
