Abstract

The performances of a current-mode Hall sensor featuring output current signals are discussed. The current-mode approach is analyzed by applying for first time to our best knowledge the spinning current technique to Hall plate working in current-mode to eliminate offset and 1/f noise. Among different geometries that have been studied and simulated using COMSOL MultiphysicsTM, cross-shaped model displayed the lowest noise and residual offset and the best sensitivity. The COMSOL results determined a behavioral model implemented in Verilog-A for simulations in the Cadence environment. Simulations results achieved in COMSOL and in Cadence environment show the potentiality, thus demonstrating the effectiveness of the approach, for a possible use of the device with remarkable performances.
