Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

Many analog sensors today are designed to operate from a single power rail but produce output signal centered around approximately half of power supply voltage, linear hall effect sensors and MEMS ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
