Magnetic field sensitive amplifier with temperature compensation

Magnetic field sensitive amplifier with temperature compensation

Reports on the use of the split-drain device in an operational amplifier configuration where the amplifier input offset voltage is modulated linearly by the incident magnetic field. The sensitivity can be adjusted by changing the closed-loop gain. With reasonable gains (10) and 50- mu A bias current...

Description
Summary:Reports on the use of the split-drain device in an operational amplifier configuration where the amplifier input offset voltage is modulated linearly by the incident magnetic field. The sensitivity can be adjusted by changing the closed-loop gain. With reasonable gains (10) and 50- mu A bias currents, equivalent sensitivities of 16 kV/AT are obtained.< >
