Current transformer as inexpensive, non-invasive timing trigger

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

Comparators target high-speed, low power, rail-to-rail swing

Analog Devices’ ADCMP60x family of rail-to-rail comparators is designed for applications that require high-speed, low power, rail-to-rail swing and high precision. The comparator family supports all ...

Comparator-Based Circuits Easily Shift Voltage Level, Flip Polarity

Because digital systems often have only a single-polarity power supply, a common problem becomes translating an opposite-polarity pulse train into a positive-or negative-pulse output. Here are some ...

Asymmetric Output Into Capacitor Load Turns Capacitor Into Ideal Diode

Comparators are great at turning little signals into large digital outputs. In the example described here, a friend wanted to detect the presence of a small 60-Hz ac signal centered on 2.5 V dc. When ...
