Abstract
The Hall probe we developed is a miniaturized analog system, consisting of two silicon vertical Hall devices, current stabilizers, amplifiers and error-correcting circuits. The output signal is 1 V/T, with an error less than 10/sup -4/ in the ranges /spl plusmn/2 T, 15/spl deg/C to 35/spl deg/C, and DC to 10 kHz. The probe features high long-term stability, low offset drift and low noise.
