Abstract

The zero-level stability, reliability and as well as the reproducibility of magnetic Hall sensors can be drastically spoiled by the offset voltage and its production spread. However, all these negative factors could be reduced using a single Hall plate and chopper stabilized amplifier stage which contains switching means for periodic permutation of the supply and output contact pairs. The present work describes the design and layout of a chopper-based monolithic single plate digital Hall sensor with a dynamic offset cancellation technique and some signal condition process
