Investigation of Linear Hall-Effect Sensors Based on III–V Compounds at Pulsed Power Supply Mode

Abstract

The article considers the application scope widening for Hall-effect sensors (HES's) based on III–V compounds. The significant HES's output voltage rise is achieved by means of transition to pulsed power supply mode. Pulses with big duty cycle result in lower HES's heating at supply current growth and corresponding pulsed Hall voltage increase. The quick theoretical data is presented, the experimental technique and the obtained results are described. The achieved high output voltage together with linearity and inertialessness of HES's enable using them for synchronous reception of electromagnetic signals.
