Abstract

SPICE macro models for magnetic MOSFET (MAGFET) devices in the saturation region are presented. By using the proposed models, the performance of several readout circuits using MAGFET devices could be predictable. In this paper, the magnetic field-to-voltage converter, the magnetically controlled operational-transconductance amplifier, and the magnetically controlled filter and magnetic-operational amplifier using MAGFET devices have been designed, simulated, and tested. The proposed readout circuits using two different CMOS processes have been fabricated. Both simulation and measurement results verify the correctness and flexibility of the proposed SPICE macro models
