The Hall effect div.tech img { width: revert-layer; max-width: 100%; } The function of a Hall sensor is based on the physical principle of the Hall effect, which was named after its discoverer, Edwin Herbert Hall (1855-1938): If a magnetic field takes af
Hall-effect probes are more expensive and sophisticated instruments used in scientific laboratories for things like measuring magnetic field strength with very high precision.Photo: 1) A typical silicon Hall-effect sensor. It looks very much like a transistor—hardly surprising since it's made in a...
CONSTITUTION:Hall effect integrated circuit consists of a Hall element HD, a differential amplifying circuit AMP which amplifies its Hall element output voltage, a Schmitt trigger circuit which shapes the waveform of the apmlified signal and an output circuit OP. These circuits are formed on the ...

(4) Latch up effect - parasitic PNPN effect Due to the parasitic transistor effect of MOS transistors (multiple transistors are formed under CMOS transistors, which may form a circuit on their own), if the circuit accidentally encounters conditions that turn on the parasitic transistor, the parasi...
