High-speed CMOS magnetic angle sensor based on miniaturized circular vertical Hall devices

We present a high-speed CMOS integrated magnetic angle sensor consisting of two 8-contact circular vertical Hall devices (CVHD). The biasing and sensing of the Hall voltage is rotated clockwise for the first device, and counter clockwise for the second one ...

High Bandwidth CMOS Magnetic Sensors Based on the Miniaturized Circular Vertical Hall Device

Mirjana Banjevic

Hall-effect devices make up by far the largest part of all magnetic sensors on the market today. The main reason is compatibility of Hall devices with modern semiconductor technology. In particular, integrated Hall sensor micro-systems fabricated in low-co ...

Miniaturized Circular Vertical Hall Device

Radivoje Popovic, Mirjana Banjevic

A miniaturized circular vertical Hall device with 8 contacts was studied in terms of its sensitivity, biasing topologies and residual offset. The geometry accounts for about 30% lower sensitivity, but offers the possibility of biasing the whole device in a ...

Magnetic field sensor measuring a direction of a magnetic field in a plane and current sensor

Radivoje Popovic, Mirjana Banjevic

A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises two sensing structures (1A 1B) that can be operated as a rotating Hall element. The two Hall elements are rotated in discrete steps in opposite directions. Such a ma ...

On performance of series connected CMOS vertical hall devices

Radivoje Popovic, Mirjana Banjevic

Series connected (stacked) CMOS vertical Hall devices were analyzed on the basis of performance of a single five contacts device biased at different common mode voltages with respect to the substrate. The uneven influence of junction field effect on residu ...
