1. Analog comparator recognizes three signal relations
   Glen Chenier
   Circuits Analogue Design Measurement Intersil ICL7650S
   Several years ago we were developing a clamp-on photometer, a hand-held instrument that could be clamped onto a communications optical fiber to indicate the presence of light, its direction of travel, and the presence of combinations of ...

2. Clamping circuit dissipates minimal power
   Carlisle Dolland
   Circuits Supply Intersil ICM7555
   The circuit in Figure 1 is a quasi-linear regulator. It functions as a source follower for input voltages greater than a preset level, determined by VR 3 . For input voltages lower than the preset level, the pass element, Q 2 , operates as a ...

3. Filter allows comparison of noisy signals
   Circuits Analogue Design Intersil LM339
   When you need to compare the dc level of a noisy signal with a reference for further processing, the output of the comparator changes in a chaotic way when the dc level approaches that of the reference. You have a choice of two classic solutions to ...

8. Bender senses shocks
   Circuits Analogue Design Measurement Intersil ICM7556
   Don Sherman, Maxim Integrated Products EDN With the aid of a simple mounting system and some soldered-on weights, a piezoelectric “bender” can detect mechanical shocks. The bender comprises a piezoelectric-ceramic element bonded to a ...

9. Optical feedback extends white LEDs' operating life
   Circuits Light Power Intersil ISL29000 EL7630
   Bjoy Santos EDN Regardless of its color, an LED's light output varies as a function of forward current and ambient temperature. As Figure 1 shows, an LED's light output can vary by as much as 150% over its operating-current range. In response, a ...
