Sensor Review, Vol.18, No.4, 1998, pp.252-257.
Abstract
- The new developments in silicon Hall sensors are highlighted. First,
basic components made by microelectronic technology are explained. They
lead to the development of high accuracy vectorial magnetic probes. Then
examples of new application like angular position sensor and current
measurements are illustrated. Finally, new concepts in order to increase
the detectivity using magnetic chopping are demonstrated. |

contactless angle measurement", IEEE Journal
Solid-State Circuits , vol. 31, pp. 1902-1907, 1996. Abstract - The
reported CMOS microsystem is the key element for accurate angle
measurements. In combination with a permanent magnet it is used for
various wear free angular positioning control systems for automotive and
industrial applications covering the full 360 degree range. The integrated
system includes a two dimensional magnetic microsensor (30 x 30 m2 active
area), offset compensation and signal conditioning circuitry. A novel
approach for the angle calculation is presented using an on-board
incremental ADC. A bitstream representing the angular position of the
applied permanent magnet is provided at the system output. The system
achieves a one degree angular resolution with 9 mW power consumption and a
permanent magnet of 100 mT. The chip is fabricated in a generic 2 m double
poly, double metal CMOS process and covers an area of 2.6 x 4.1 mm2. |

interface for a 3D magnetic sensor, Proceedings
of IEEE International Symposium on Circuits and Systems (ISCAS `97) ,
Hong Kong, pp. 1-4, 1997.
Abstract - This
paper presents a high resolution low-power smart system for 3D magnetic
field monitoring. The magnetic sensors, integrated on-chip, need a bias
current of a few mA to achieve the required resolution. Nevertheless, the
proposed 12 bit A/D converter allows pulsed operation of the sensors
with a duty cycle as low as 4 10-5, thus keeping the system power
consumption below 1 mW. The A/D converter operates with 500 kHz
clock frequency and achieves a DNL below 0.2 LSB and an INL below 0.5 LSB
in worst case simulations. A prototype of the system has been integrated
in a 1.2 mm CMOS technology. |

Abstract - We
present a CMOS microsystem which is used for accurate contactless angle
measurements in combination with a permanent magnet (1 degree
measured resolution). The integrated system includes a 2D-magnetic
microsensor, temperature and offset compensation circuitry as well as
signal conditioning for the angle calculation. |
